This tester was used between 1950 and 1980's. As part of the Occupation, Health and Safety requirements, equipment used to monitor the performance of electricity producing generators, regularly, hand held testers were used to check the insulation and the "earth" pin were up the the required operational levels. As the generators and their ancillary monitoring equipment was spread over a large area and cumbersome to service small hand held devices were required. These had to always be safe for the user to operate. A selected range of high quality meters were recalibrated every two years in the Meter and Calibration Laboratory at Yarraville(near Melbourne) This meter is very significant to The Kiewa Hydro Electricity Scheme because it was an integral part of maintaining the electricity producing water driven generators of the power stations. The reason why this meter was so essential is that provided the safety check on equipment used to monitor each Hydro Generator that they were complying within the grid network parameters. Grid parameters are set so that if there is an electrical fault on the system, that fault can be attended to with a very small change in the output stability of each generator. It is essential that the voltage of the network remain within the set limits. Generators are at Dartmouth, Mackay, Clover, West Kiewa, Yarrawonga, Cain Curran and three Power Stations in the Thornton area.This hand driven current generator produces 500 volts by winding the handle(on funnel curved side) to keep the voltage constant(one minute per test). The whole body is made from caste aluminium. One of the functions of this meter is to test the isolation resistance of any equipment being tested. This is to see if that equipment is safe to handle(no electrical shocks). The second function is to test the earth pin of any portable electrical equipment. The turn key on one side can direct which function is required(marked insulation or continuity). On the top side(enclosed in a glass fronted marked scale) is a continuity scale(top) and an insulation scale(bottom). This is covered , when not in use by "flip up" lid with manufacturer's details and name of the instrument. Opposite the winder are two screw tight knobs. One marked earth(left side) and one marked line(right side). On the top and next to the glass windowed scales in a post manufacture SEC Vic equipment equipment ID number.

When this AVOMETER was being utilised in the early 1950's it was at the "leading" edge of electrical measuring instrumentation.The first meter was produced by Automatic Coil Winder and Electrical Equipment Co. in 1923. This model was produced in the time from 1933 to 1951 when it was superseded by the most popular model, Model 8 (1951 to 2008).This AVO meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one measuring unit. By using a "one fits all" unit, the carrying of separate measuring devices was reduced considerably. The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to minimise the weight of equipment carried by electricians and technicians was of the utmost relevance. The significance of this meter to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. This equipment shows how the boost of "modern" equipment into the area because of the "Hydro Scheme" was facilitated a lot faster than would have taken under "normal" evolutionary time. The speed of information on all "new technology" had a relatively slow assimilation rate to those living in rural communities. This AVOMETER is a Model 7 MKII, production pre 1951. This meter measures electrical Amps, Volts and Ohms and has two internal batteries for its power. The main casing is made from aluminium with a bake-lite front. The front has a "window" detailing, with a needle pointer, the amount of electrical power being tested. There are two big dial switches, detailing Direct Current(DC) and Alternating Current(AC) when reading measurements of Ampere, Voltage and Ohms for power. This meter took the place of three or four meters used earlier. Modern meters (2000 onwards) have become digilised and are considerably lighter in weight and smaller. There are two electrical connection leads (one black and one red) each has a removable clasp and is 125cm long.Molded on the front centre panel " UNIVERSAL AVOMETER".

This Timing Relay is quite a large (industrial type) apparatus. The Timer is started by having a voltage of 250 volts direct current (as supplied by batteries). A DC motor then rotates driving into a clockwork mechanism, the output of which is an arm rotating at the same speed as a minute hand on a clock. Attached to this arm is a mercury switch which tips and makes an electrical circuit operate in a sequence control system. The sequences that use these timers are when starting and stopping Hydro Generators. They check that the machine has connected to the power system grid before 20 minutes duration. Brakes must go on for a set time when shutting down a generator slowing at the right speed as measured by this apparatus. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This Timing Relay apparatus is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a relay apparatus, it was however part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This Hydro Scheme was instigated by "the Government of the day" as a bold move and was the major force behind the acceptance of World War II refugee and "technical" workforce. Inclusion of skilled and unskilled migration into the Australian environment was of a higher priority than a selective quota system of later years.. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual, multi-cultural diversity of later years.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

FLETCHER RUSSELL & CO. LTD/ WARRINGTON MANCHESTER & LONDON Thomas Fletcher (1840-1903) had established a gas appliance manufactory in Thynne Street, Warrington by the 1880s. By 1895 the company had become Fletcher Russell and Co Gas Engineers, his firm having merged with Alexander and William Russell of Pendleton Iron Works. In 1950, the firm merged into Radiation Ltd which was later acquired by 'TI New World. In the early 1880s Thomas Fletcher was a registered dentist who went on to found a dental apparatus manufacturing business. He later diversified into producing equipment for blacksmiths, foundries, forging and other sectors. The company had grown to 900 employees in 1914. These foot-operated bellows were for pumping gas to keep the patient relaxed while the dentist worked on their teeth. They were later modified for a variety of uses where a continual flow of air was needed.These bellows are representative of a range of devices developed in the late 19th Century to assist in manufacturing. They were donated to our collection by a Wodonga resident.A set of foot bellows made from timber, metal and leather. The bellows were activated by pressing up and down on the metal step-shaped lever at the front. The air outlet on one side would have a hose attached to it to direct the air current to wherever it was needed. The bellows are made from leather. The manufacturers mark is attached to the top within a metal circle.On top of Bellows in a circle: "FLETCHER RUSSELL & CO./ WARRINGTON/ MANCHESTER / LONDON"foot bellows, fletcher russell & co. ltd.

Megger as the device was called, is in fact its brand name. It is a device that supplies a DC (direct current as per car batteries) voltage to enable testing of electrical apparatus. This particular device produces 250volts DC when the handle is turned vigorously. If an electrical device, such as a kettle or toaster, blew a fuse or tripped a circuit breaker, when switched on, then it must be checked electrically before any more use. Following the repair of the faulty item a megger would be used to check if either of the AC 240volt plugs leads were touching the metal case (earth). The output leads of the megger would be connected with one to the earth (metal case) and the other to each of the power connections in turn. A good megger reading of 50,000 ohms (resistance) would enable the device to be returned to service. A reading of zero ohms resistance would mean that it would again blow a fuse, and was therefore unsafe to use. In the electrical industry e.g. the former State Electricity Commission, a megger would be used to test lots of similar item in sequence. Because of the vigorous job of winding the handle, two persons were often used to save time. One would crank madly whilst the other shifted the leads. This particular megger is of a small voltage, but other meggers are bigger and have a few ranges of DC voltages able to be selected. The optimal megger for large Generating machines was motor driven megger. This was applied to the device being tested for a duration of approximately 30 minutes with reading of the resistance taken at regular intervals.All equipment belonging to the State Electricity Commission of Victoria was labelled with a metal plaque attached to it. The SECV constructed the Kiewa Hydro Electric Scheme in the Upper Kiewa Valley and on the Bogong High Plains. The scheme began in 1938 and finished in 1961 when this megger was used and also possibly later as the SECV remained to maintain and operate the Scheme. This megger is of significance in relation to the advancement of technology.A rectangular box in dark brown bakerlite casing. It has an agent's plaque fixed to the left of the face and on the right is the marker's recessed stamp. In the middle in a transparent window so the level of ohms can be read.

Until late 1925, all record players reproduced sound by purely mechanical means and relied on a so-called "amplifying" horn to efficiently couple the vibrations of the stylus and diaphragm to the space occupied by the listeners. In 1906, the Victor Talking Machine Company, Columbia's arch competitor, introduced a line of models in which the horn and other hardware were concealed within a cabinet, made to look like fine furniture rather than a mechanical device. They named the new style a "Victrola". It quickly proved to be very popular and successful. Other makers, adopting the distinctive suffix, introduced their own "-ola" internal horn machines, such as Edison's Amberolas and Columbia's Grafonolas. They were soon outselling the external horn models. At first, like nearly all other early record players, all Grafonolas were driven by a spring motor that the user had to wind up with a crank before playing a record. In 1915, Columbia began to introduce electric-motor-driven models, as a majority of urban areas had been wired to electrical grids. The electrified Grafonolas supported both alternating and direct currents from 110 to 220 volts. Electrified Grafonolas never gained the popularity enjoyed by the spring motor-driven versions due to substantially higher prices and a lack of electrical service in rural areas. Grafonolas were manufactured under the 1886 United States Letters Patent No. 341,214 which Columbia Graphophone company acquired through its predecessor American Graphophone Company. Two models were available; a portable table model and bigger stationary floor model, offering limited mobility through the application of casters. The most notable table models included Grafonola Favorite introduced in 1911 and Grafonola Savoy introduced in 1915. The most notable floor models included Grafonola Symphony Grand introduced in 1907, Grafonola Regent introduced in 1909, Columbia Mignon introduced in 1910, Grafonola Princess introduced in 1911, Columbia Colonial introduced in 1913. Various period Grafonolas were introduced in 1917 to cater to an increasingly prosperous clientele. Columbia Phonograph Company began to manufacture a series of ornate, limited edition period machines. These were highly priced (some as high as US$2,100 ) special orders that provided consumers with options to choose styles which matched their interior décor. Although the Gramophone does not have a large monetary value, it is of social significance as it demonstrates the progress made in audio reproduction from the first Edison cylinder machines to improvements that allowed ordinary people to be able to buy music discs and enjoy music in their own homes.

Ash KEATING Among fifteen finalists this artwork won the 2012 Guirguis New Art Prize, a prestigious national acquisitive biennial art prize administered by Federation University Australia. The Guirguis New Art Prize (GNAP) is a national acquisitive $20,000 contemporary art prize which presents a selection of Australia's most exciting contemporary artists with works that explore and embrace new ways of artistic expression, utilising existing mediums and new technologies in innovative ways. Initiated and generously supported by local Ballarat surgeon Mr Mark Guirguis, this prestigious art prize is administered by the Federation University Australia (FedUni). As a local philanthropist and art collector, in developing the Prize, Mark Guirguis' aims were to celebrate the significance of the arts to communities and to Ballarat, emphasising contemporary art and 'living' culture, and to highlight FedUni's Arts Academy. Artist Ash Keating works across a conceptual, site-responsive and often collaborative art practice that incorporates painting, sculpture, installation, video, performance and public interventions, and has referenced a wide range of social and environmental issues within his art. Frequently working beyond the gallery, and often harnessing community narrative and energy, his work also draws upon myth, ritual and ceremony. 'West Park Proposition', 2012, is a three channel and screen video installation, utilising multiple camera video documentation of an endurance painting intervention undertaken on the morning of 01 September 2012 on the east facing wall of a newly built tilt-slab industrial building, situated on the direct edge of the current urban and rural boundary in Truganina, Victoria. The multi-screen work documents an endurance guerilla-style action painting intervention and ritualised painting performance in which a symbolic violence is enacted against a storehouse of commodity production and consumption. Upon winning the award artists Ash Keating said; “The work was made near Ballarat on the Deer Park bypass. It is an aesthetic comment about the way these new tilt-slab industrial buildings spring up without caring for the environment." The work, which took eight hours to create, was about reclaiming the space from “cost-effective architecture” without any aesthetics. The inaugural judge for the Prize, Jason Smith, Director, Heide Museum of Modern Art (MoMA) said, "Selecting the winner of this inaugural GNAP was exhilarating and excruciating: exhilarating because the seriousness of each artist's enterprise, and their uncompromising resolution of concepts, has created an inaugural exhibition of exceptional power. This first GNAP is a survey of some of the most poetic and provocative imaginations working in Australia today. Selecting one winner from such a show in which each of these artists has in some way transformed my thinking about the world was the excruciating part. Ash Keating's work West Park Proposition, 2012 kept drawing me back in the several hours I spent viewing the works. It simultaneously affirms the political and critical role of the artist as a key agent of change and action, and someone who reminds us of the beauty and resilience of humanity and nature in the face of unrelenting change. As a work combining performance, collaboration and hope, Keating's West Park Proposition is a work of immense and compelling poetry."artist, artwork, keating, ash keating, guirguis, guirguis new art prize, gnap, gnap13

Officers are eligible for the award provided they have served a minimum 12 years in the ranks. The riband is dark blue and maroon with white edges. This medal ceased to be awarded in Australia in 1975 when it was replaced by the National Medal (and sbsequently the DFSM and DLSM) in the Australian system of honours and awards. http://www.heritagemedals.com.au/medals-1/service-long-service/air-force-long-service-and-good-conduct-medal.html History of the RAAF Dental Branch It took six years following the formation of the RAAF in 1921 for the first Dental Clinic to be established at Point Cook, Victoria. On 10th June 1927 Flying Officer James Carl Rosenbrock commenced work as an RAAF Dental Officer for the FlyingTraining School at Point Cook. As personnel numbers were still relatively small, Rosenbrock was also responsible for the dental care of all Victorian RAAF units, which involved treating members at 1AD Laverton, as well as Air Force Headquarters at Victoria Barracks in Melbourne. As Army Dental Officers were currently caring for RAAF personnel at Richmond, NSW, the Senior Dental Officer of the 3rd Military District in Victoria (SDO 3MD) requested through the military board that a similar arrangement be established, where that the newly appointed RAAF Dentist provide part time dental services to the Army units stationed at Queenscliff. This was seen as an effective reciprocal arrangement, with both units having a Dental Officer in attendance for, in total, around 3-4 weeks a year. Rosenbrock continued to serve as the sole RAAF Dental Officer until the middle of 1933, when the Air Board asked for his service to be terminated following ‘behaviour unbecoming of a RAAF officer'. He had borrowed several sums of money, of around 40 Pounds or so, from junior ranks on base (as well as from the Regimental Sergeant Major) and had failed to pay the money back. He was replaced by a fellow Victorian, FLGOFF Norman Henry Andrews, on the 18th Sep 1933, who went on to become our first Director of Dental Services, and was instrumental in establishing the organisations and conditions of the Branch that are still present today. Through a fair amount of persistence and hard work on the part of Norman Andrews, the RAAF Dental Branch began to expand from 1937, with the introduction of 2 additional positions, at RAAF station Richmond, and at the FlyingTraining School at Point Cook. This gave the RAAF 3 uniformed Dental Officers, which was expanded to 5 in the months leading up to WW2. 4 of these Dental Officers were based in Victoria and 1 at Richmond, with the other two RAAF units being cared for by the Army (as in the case of Pearce in WA) or by civilians (as in Darwin). With the sudden increase in RAAF personnel required at the outbreak of WW2, the number of RAAF Dental Officers increased dramatically, from 5 in 1939, 28 in 1940, 64 in 1941, 147 in 1942, 193 in 1943, 219 in 1944, and peaking at 227 in 1945. RAAF Dental Officers were required to work in a variety of locations, both in and out of Australia. Between 1940 and 1942 a massive construction programme occurred, with new dental clinics being established around Australia. Priority was given to aircrew training units in order to get these personnel dentally fit for operational deployment, but Dental Officers could equally find themselves posted to recruit depots, fixed stations, medical clearance stations, mobile dental sections, and RAAF and civilian hospitals. RAAF Dental Officers were posted to the large dental centres at Ascot Vale (Vic) and Bradfield Park (NSW) when first appointed, where they received military and clinical training, before being deployed to their needed location. Mobile Dental Units When Japan entered the war in 1941, the rapid deployment of troops to northern operational areas with less than ideal dental fitness was extremely high. As a result, the RAAF deployed a range of mobile dental units, either alone or with medical sections, to support the increasing number of isolated deployed personnel within Australia and overseas. There were three types of mobile unit used: a. Mobile Dental Unit – relied on using either a semi-trailer to get around or by building a surgery directly on to the truck chassis, and installing hydraulic chairs, units, x-rays, and laboratory equipment. They were able to move around between small units, such as RAAF radar stations, where they could plug into the local power supply and work immediately. b. Transportable Dental Units – used for stops of longer duration, where field equipment was carried in panniers from one unit to another by road or rail and housed in whatever accommodation was available at the destination. They were often carried within Australia on Tiger Moths and Dakota aircraft. c. Itinerant Dental Units – in some areas, the dental equipment was installed at the RAAF unit and the Dental Officer and their staff would travel from unit to unit, using the equipment available at each location. RAAF Dental BadgeAs the war developed in Europe, it soon became obvious that the RAF Dental support was not capable of supporting the increasing numbers of RAAF aircrew that were being sent for service with the RAF, with only enough Dental Officers available to provide one to every 2000 men ( instead of the preferred 1 to 600). As a result, the RAAF provided a mobile dental unit, fitted out in a caravan and pulled by a Ford V8 Coupe, to travel around England in support of RAAF personnel at various squadrons. Some degree of tact was needed to ensure that the RAF did not take this as a comment on the treatment they were providing, but it proved successful in maintaining a satisfactory state of dental fitness in RAAF personnel, and a second mobile unit was soon dispatched. They were also set up with a laboratory on board as well as the surgery, which was a major difference between the RAF and RAAF, as the RAF did not provide dentures for their troops (the RAAF would, providing they had served for 6 years). In 1943 the RAF was no longer able to provide Dental support to Australian troops in the Middle East, which resulted in the need for a transportable dental unit to be deployed from Australia. It functioned in a similar manner to the RAF, by moving from one squadron to another. It served in the Middle East and Africa, from Cairo across North Africa, to Italy, and eventually back to England to treat returned prisoners of war. GPCAPT Norman Andrews The growth and development of the RAAF Dental Branch owes a debt to one man in particular, GPCAPT Norman Andrews. As the second RAAF Dental Officer to enlist on 18 Sep 1933, Andrews became the principal architect of the structure and organisation of the RAAF Dental Branch leading up to and during WW2. Until early 1940, the RAAF Dental Branch was administered by the Director of Medical Services (Air), which placed it under the control of the Army Medical staff. The Army would provide their Inspector of Dental Services for advice whenever needed. In April 1940, the RAAF Medical service separated from the Army, resulting in the control of the RAAF Dental Branch shifting back to the RAAF. Andrews became the first Director of Dental Services, when the position was created in 1943 as recognition of the higher profile the Dental Branch was now playing in the RAAF Medical service. Until this time, Andrews's title had been as the Dental Staff Officer to the RAAF Medical Service. Andrews was responsible for the establishment of the war-time structure of the Dental service, establishing new dental centres at all major bases, creating mobile and transportable dental units, ensuring the continual growth of the Branch, maintaining professional development of staff through the establishment of a professional journal, and by organising renowned lecturers to speak at RAAF bases. He also believed in visiting as many dental units as possible to see for himself what conditions were like and to talk first-hand to staff in remote units. His itinerary during the war years, both in and out of Australia, shows a large number of trips in a variety of modes of transport in order to reach remote areas where units were serving. He was promoted to GPCAPT in July 1944, as the numbers of Dental Officers soon peaked at 227 towards the end of the war (1 GPCAPT, 9 WGCDRs, 60 SQNLDRs, and 157 FLTLTs). After the war, with the reduction in RAAF personnel required in uniform, the Dental Branch also reduced its numbers significantly. By 1947 there were only 18 Dental Officers serving (many part-time), with 1 GPCAPT, 1 WGCDR, 10 SQNLDRs, and 6 FLTLTs, and only 13 by 1950. With the decrease in Branch personnel numbers, the ‘powers to be' saw fit to reduce the Director of Dental Service rank to WGCDR, and as a result Norman Andrews found that in order to continue serving in the RAAF he would have to wear a reduced rank. This appears to have been a contributing factor in his decision to discharge at the relatively early age of 43 and accept an administrative job as Director of the Victorian Government's School Dental Service. Norman Andrews holds the proud honour of being the founder of the RAAF Dental Branch, which during the war was instrumental in educating servicemen of the importance of dental health and maintaining the dental fitness of troops in a variety of areas. Dental Orderlies (Assistants) The dental orderly mustering was first introduced in 1937. Until that time, medical orderlies were assigned to assist the Dental officer with their duties. As early as 1931 it had been noted by both RAAF and Army Dental Officers working in Victoria and Richmond that a lot of the troubles they were having would be solved by appointing a permanent Dental Orderly. Often they would find that the medical orderly they were assigned was a different one each day, and as a result the administration and work in general was very inefficient. By 1937, with the increase in Dental Officers to 3, it was realised that a Dental Orderly mustering needed to be created. Dental Mechanics/Technicians Before WW2, dental laboratory work was provided by civilian laboratories, as most RAAF units were stationed around metropolitan areas. At this time, service personnel were still required to pay for their own dentures, unless they had served for six years or had their dentures damaged during performance of their duties. In July 1940, mainly in response to the development of more remote RAAF dental units and the increasing demand for dental prostheses, the Dental Mechanic mustering was established. Unfortunately there was a very limited pool of civilian dental mechanics to recruit from, and as a result the RAAF set up a training school at Laverton (which was later moved to Ascot Vale) in June 1941 which conducted an intensive 6 month course in Dental mechanics. Dental mechanics were quickly in demand. In all fixed and mobile dental units at least 1 Mechanic was supplied for each Dental Officer, and indeed the RAAF supplied Dental Mechanics throughout all its deployments, something the RAF were unwilling, or unable, to do. Two grades of dental mechanic existed: the Senior Mechanic (with the rank of NCO), who was competent in all phases of laboratory work; and the Junior Mechanic, who could only handle routine work and not more advanced denture work. The progression to Senior required a further trade test in techniques including setting up, clasp-forming, casting and backing teeth. During the course of the War, two special courses were held for Mechanics. The first, directed at senior mechanics so that they could instruct others, was in 1942 when Acrylic Resin was first introduced as a denture base material, as an alternative to the current option of vulcanite. Later, towards the end of the War, a ‘refresher' course was provided for those that had served for the greatest period of time in order to allow them retraining in techniques that they had not practised during their service and which were common in civilian life. This included cast base dentures, crowns and bridges, partial dentures, and retainers. Towards the end of the War, a course was held with WAAAF trainees to train them as Mechanics. However, as the War was soon to end they never had the opportunity to progress within the mustering to become Senior Mechanics. The RAAF Dental Branch has survived 75 years of turbulence, with reviews of its viability occurring regularly every few years from as early as 1937.

This testing voltmeter recorder was last certified by SEC Vic laboratories on the 17/4/77. It was used extensively as mobile recorder placed for periods of one month at locations experiencing unacceptable fluctuations of power. These locations would cover the North East regions of Victoria. They cover voltage drops at domestic and business properties especially those that were experiencing regular fluctuations(daily) at approximately the same time of the day. As the electrical network is required to operate within a set level of voltage, fluctuations outside of this has to be investigated and necessary remedial action taken. This is especially so for rural properties where power "drainage" can occur through animal/bird and tree interference. It can also be the result of defective wiring and overloading at peek operational times (milking machines).This mobile voltage recorder is very significant to the Kiewa Valley because it highlights the difficulties that can occur in maintaining a power supply that experiences fluctuating power demands by the rural industries that it supplies. The requirement of a mobile testing apparatus to cover the various sections in the Kiewa Valley and other rural areas in the northeast region is one of necessity as electricity once connected to a rural property is a labour saving supply as generators on rural properties require a higher degree of maintenance an ultimately at a higher cost. The testing of the SEC Vic supplied electricity to rural properties,those who had previously run on generators, had to be quick and unassuming with certainty of correct supply levels.The mechanism of this voltage recorder has been installed(by the manufacturer) into its own protective wooden box. This box has a front (swing open) lockable section which permits direct access to the installed measuring equipment (for servicing and data collection). The top section of the box has two screw on terminals for access to the machine being tested. This tester has its own inbuilt ink supply facilities and a mechanical clockwork device that unwinds a roll of paper onto a second roll at a rate of 10 mm per hour. The recording chart is marked with time slots against voltage. There is a recording arm which has an ink pen at the end. Both arm and pen carry the ink supply from the ink reservoir, located on the left side of the cabinet door in specially constructed bottle holder( three small bottle capacity). To record a suspect power problem to a home or business establishment the voltmeter is connected to a power supply outlet being tested and wind the recording clockwork mechanism (gives a four week running time). Before leaving the recorder in situ the electrician checks to see if the chart is recording the correct voltage and that the clock mechanism is advancing correctly.On the front of the access "door" at the top a metal label "RECORDING AMMETER" below this "MURDAY SYSTEM" below this "ALTERNATING CURRENT" and below this the manufacturer's registered number "No. 139156" Below this is a metal tag with State Electricity Commission of Victoria Electrical Engineer's Section equipment number "338" Below these tags and above the viewing window is the manufacturer's dtails "EVERSHED & VIGNOLES Led LONDON"sec vic kiewa hydro scheme, alternate energy supplies, alpine feasibility studies temperature, rainfall, power outages

When scrimshaw is mentioned, most people think of carving on sperm whale teeth only. But scrimshaw also includes engravings on skeletal whale bone–such as the jaw bone, called panbone–and ivory from other marine mammals such as walrus. Although scrimshaw is widely associated with nautical themes and designs of the 19th century whaling industry, vintage scrimshaw was also produced as tribal art in many cultures. Today, scrimshaw is recognized as a unique medium in which present-day artists have developed their own modern themes. Scrimshaw reproductions may take several forms. There are - New carvings on genuine ivory or bone with the deliberate intent to create an "antique” - New carvings on genuine ivory or bone sold as signed and dated contemporary art - Clearly marked synthetic museum reproductions and mass marketed - Unmarked synthetic replicas Painstakingly carved deliberate replicas are directed towards the scrimshaw collector and seldom appear in the general market. Pieces of contemporary art and museum copies are usually clearly marked and openly sold for what they are. The biggest problems in the general antiques market are the mass produced synthetic reproduction pieces, such as this item, that can be mistaken for the genuine item. The scrimshaw is a modern reproduction of a typical scrimshaw scene and engraved onto a synthetic substance. It has been created as a decorative piece and is currently displayed as a representation of the craft of scrimshaw.Scrimshaw carved on a non-natural material in the shape of a whale tooth.

Gas lamps worked by heating something called a 'mantle' with a gas flame. The mantle then glowed brightly, lighting up the room. Lamps had either two chains, for a ceiling-mounted lamp or a tap for a wall-mounted burner to turn off the gas. These chains or taps could also adjust the flow of the gas and hence the brightness of the mantle. Before Carl Auer von Welsbach invented the gas mantle in the 1890s, all gas lights in homes and street lights had simple gas jets that pointed upwards. In the home, these lights were covered with glass globes and had an overall ornate look making the lamp ascetically pleasing and protecting the flame from being blown out. However, this arrangement was extremely inefficient: To get as much light as possible, the gas had to be turned fully up, resulting in large sheets of flame rising towards a ceiling. Also, because the lamp had to be point upwards, the illumination was directed upwards, i.e. at the ceiling rather than where it was needed. So the usable light for a given amount of gas was minimal but the invention of the gas mantle eventually changed this. It enabled gas lights to have a small flame and to direct their light downwards. The item is significant as it is part of a very ornate gas lamp wall bracket from the late 19th to early 20th century. Its provenance is currently unknown and at this time cannot be associated with a historical event, person or place and the item is assessed as a collective asset.Gas lamp wall bracket; part of a gas lamp.

Prue Sanderson, in her groundbreaking ‘City of Kew Urban Conservation Study : Volume 2 - Development History’ (1988), summarised the periods of urban development and subdivisions of land in Kew. The periods that she identified included 1845-1880, 1880-1893, 1893-1921, 1921-1933, 1933-1943, and Post-War Development. These periods were selected as they represented periods of rapid growth or decline in urban development. An obvious starting point for Sanderson’s groupings involved population growth and the associated economic cycles. These cycles also highlighted urban expansion onto land that was predominantly rural, although in other cases it represented the decline and breakup of large estates. A number of the plans in the Kew Historical Society’s collection can also be found in other collections, such as those of the State Library of Victoria and the Boroondara Library Service. A number are however unique to the collection.Subdivision plans are historically important documents used as evidence of the growth of suburbs in Australia. They frequently provide information about when the land was sold on which a built structure was subsequently constructed as well as evidence relating to surveyors and real estate and financial agents. The numerous subdivision plans in the Kew Historical Society's collection represent working documents, ranging from the initial sketches made in planning a subdivision to printed plans on which auctioneers or agents listed the prices for which individual lots were sold. In a number of cases, the reverse of a subdivision plan in the collection includes a photograph of a house that was also for sale by the agent. These photographs provide significant heritage information relating house design and decoration, fencing and household gardens.In 1928, five residential allotments bordering Segtoune and Windsor Streets were advertised for sale as part of a subdivision. Four of the blocks faced Segtoune Avenue. The auctioneers proclaimed the advantages of the sites: ‘Situate one minute from the High Street Electric Tram, which now runs direct to Spencer Street via Bridge Road and Flinders Street. Opposite the East Kew Railway Station (Outer Circle Line), which may be reopened In connection with the new Line from Kew to Doncaster; Adjacent lo the Kew Recreation Reserve, Sports Oval, and Swimming Bath; Half Minute from the Shopping Centre of East Kew, Accessible to the State School and Other Educational Centres’. The Harp of Erin Hotel and the route of the Outer Circle Railway line are marked on the plan. The Recreation Reserve and Sport Oval refer to Victoria Park. The Swimming Baths were located on the site of the current Kew Recreation Centre.subdivision plans - kew, segtoune street -- kew (vic.), windsor street -- kew (vic.)
