Sir Edward Mitchell was the chairman of the Edward Wilson trust, which enabled the building of the Braille Library during a time of great economic turbulence due to the last months of World War 1. This commemorative trowel was given to him in thanks for his (and the trust's support) of the project, which would ultimately provide a great resource to blinded soldiers who were prepared and able to learn Braille. In addition to the area housing the Braille collection itself, an entrance hall, reading room, secretarial office and hall also provided space for reading, administration of the collection and opportunities for social or recreational activities.1 silver plated trowel with handle inside boxPresented to Sir Edward Mitchell K.C., K.C.M.C. on the occasion of his laying the foundation stone of the new library for the Victorian Association of Braille Writers October 28th 1918.

Currency - One Pound Note, John Ash, 1938 - 1948
John Ash succeeded Thomas Harrison as the Australian Note Printer in 1927 and oversaw the printing of a new series of banknotes, known as the Ash Series. First issued between 1933 and 1934, the new banknotes sought to improve the currency's resistance to counterfeiting. A special watermark was created to increase the security of the new series. Shaped as a medallion, the watermark showed the profile of Edward, the Prince of Wales. A new portrait of the King was also introduced, depicting him frontally rather than in profile as he had appeared in the prior banknotes of the Harrison Series (1923-1925). The back of each denomination contained an individual vignette that reflected a sector of the country's economy. The wool and agricultural industries were represented, as they had been in the first series of the nation's banknotes (1913-1914), and they were joined by manufacturing and commerce. The prominent British sculptor, Paul Montford, contributed to the design of the new series. Recognised for his sculptural works on the exterior of Melbourne's Shrine of Remembrance, Montford was commissioned to produce relief sculptures that formed the basis of the banknotes' vignettes. His sculptures were translated into wash drawings by Frank Manley, the artist and engraver for the Commonwealth Bank's Note Printing Branch. Manley accentuated the sculpture's three-dimensional qualities with deep shadows and touches of illusionism. A sheep in Montford's pastoral scene, for example, stands forward from the frame as if entering the viewer's space to escape branding and Manley preserves this visual conceit in his drawing. Whereas the printing of the previous series of Australian banknotes had been criticised for its poor definition, the sculptural basis of the Ash Series clarified the banknotes' imagery. During a period of record unemployment, the scenes emphasised the strength of the human figure in gestures of labour, evoking classical, heroic qualities in their poses. The sculptural forms suggested stability in the turbulence of the Great Depression and imparted a sense of solidity to paper currency. - museum.rba.gov.auCommonwealth of Australia paper one pound note in green and white tones depicting graphics and text.

Accessory - Gold Cross, Bef. 01-06-1878
The gold cross was discovered by Victorian scuba diver Julie Wilkins, who had already experienced more than 500 dives in Australia and overseas. She was holidaying in Peterborough, Victoria, and looking forward to discovering more about the famous Loch Ard ship, wrecked in June 1878 at Mutton Bird Island. The fast Glasgow-built clipper ship was only five years old when the tragedy occurred. There were 54 people on board the vessel and only two survived Julie's holiday photograph of Boat Bay reminds her of her most memorable dive. Submerged in the calm, flat sea, she was carefully scanning around the remains of the old wreck when, to her amazement, a gold coin and a small gold cross suddenly came up towards her. She excitedly cupped them in her hands, then stowed the treasures safely in her wetsuit and continued her dive. She soon discovered a group of brass carriage clock parts and some bottles of champagne. It was a day full of surprises. The items were easily recognisable, without any build-up of encrustations or concretion. Julie secretly enjoyed her treasures for twenty-four years then packed them up for the early morning train trip to Warrnambool. After a short walk to Flagstaff Hill Maritime Museum and Village, her photograph was taken as she handed over her precious find. She told her story to a local newspaper reporter, lunched a café in town then took the late afternoon train home. Her generous donation is now part of a vast collection of Loch Ard shipwreck artefacts, including the gold watch and the Minton Majolica model peacock. The small decorative cross dates back to on or before 1878, when the Loch Ard had set sail. The loop and ring have been added, perhaps as a pendant, pocket watch accessory or similar purpose. It may have been worn for ‘good luck’ or a ‘blessing’ on the long journey to Australia, where ships had to carefully navigate the treacherous Bass’s Strait before arriving at their destination of Melbourne. Sadly, many met their fate on that short stretch of ocean aptly named the Shipwreck Coast. The cross is very recognisable even though it was exposed to the wrecking of the ship, its consequent movement, and the sea's turbulence. Its scratched, pitted and worn condition, and the damage near the loop, is part of its story. The red-brown-black discolouration is similar to that found on other gold coins, sometimes called the ‘corrosion phenomena’. Studies suggest the possible cause is contaminants in the minting process reacting to the coins’ environment. Three edges of the cross have slightly raised narrow ridges of gold which could have been cause by the gold being cast liquid gold into a mould.This gold cross pendant is significant as a symbol of Christianity, a sign of hope and safety, and a sample of the religious following on board the Loch Ard, although not everyone wears a cross for this reason. This cross is a sample of jewellery owned by people migrating to Australia in the late 19th century. The cross and the guinea recovered together from the wreck of the Loch Ard are made of gold and help interpret the financial status of some of those on board.Gold cross; yellow gold with decorative hand engraved foliage design on the front, fitted loop and ring on top. The simple Latin or Roman variation of the cross, with an elongated vertical arm, has no figure on it and the reverse has no decoration.

Currency - Guinea Coin, The Royal Mint, 1793 George III Spade Guinea, 1793
The coin was discovered by Julie Wilkins, a Victorian scuba diver who had already experienced more than 500 dives in Australia and overseas. She was holidaying in Peterborough, Victoria, and looking forward to discovering more about the famous Loch Ard ship, wrecked in June 1878 at Mutton Bird Island. The fast Glasgow-built clipper ship was only five years old when the tragedy occurred.

After a short walk to Flagstaff Hill Maritime Museum and Village, her photograph was taken as she handed over her precious find. She told her story to a local newspaper reporter, lunched a café in town then took the late afternoon train home. Her generous donation is now part of a vast collection of Loch Ard shipwreck artefacts, including the gold watch and the Minton Majolica model peacock. The coin is a British 1793 George III Gold Spade Guinea. It was already 83 years old when the Loch Ard had set sail. The loop and ring have been added, perhaps as a pendant, pocket watch accessory or similar purpose. It may have been worn for ‘good luck’ on the long journey to Australia, where ships had to carefully navigate the treacherous Bass’s Strait before arriving at their destination of Melbourne. Sadly, many met their fate on that short stretch of ocean aptly named the Shipwreck Coast. The coin is very recognisable even though it was exposed to the wrecking of the ship, its consequent movement, and the sea's turbulence. Its bent, scratched, buckled, split, dinted and worn condition is part of its story. The red-brown-black discolouration is similar to that found on other gold coins, sometimes called the ‘corrosion phenomena’. Studies suggest the possible cause is contaminants in the minting process reacting to the coins’ environment. The GEORGE III GOLD SPADE GUINEA: - The British Guinea was introduced in 1663 and was circulated until 1814. It was made of 22 carat gold, was 25 to 26 cm in diameter and weighed 8.35 grams. It had a value of 21 British shillings. The guinea coin ceased circulation after 1816 and was replaced by the one-pound note. However, the term ‘guinea’ continued to represent 21 shillings. King George (1738-1820) had six gold guinea designs minted during his reign from 1760 and 1820. Each of the six had different obverse portraits, all facing the right. There were three different reverse sides. The Spade Guinea was the fifth issue of the coin, introduced in 1787 and produced until 1799. The reverse shows a royal crown over a flat-topped shield with the Royal Arms of Great Britain, used in Scotland between 1714 and 1800. The shield images are, from left to right, top to bottom, the Arms of England and Scotland, the Arms of France, the Arms of Ireland, and the Arms of the House of Hanover. The Gold Guinea is also part of Australia’s history. It was the first coin mentioned in the announcement of Governor King of New South Wales his Australian Proclamation of a limited variety and denomination of coins accepted for use in the Australian Colony. The historic and decorative George III Spade Guinea has been reproduced for special collections of coins. However, replicas and imitations have also been made as souvenirs for tourists, as gaming tokens and chips for gamblers, and as ‘fake’ coins for profit. These coins differ in many ways; they may be only half the weight of the genuine coin. Often have a small stamp on the obverse with “COPY” or the manufacturer’s name or initials. Some have scalloped edges, some have dates that are different to the original dates of issue, and some even have text in Latin that translates as something very different to the original coin.The King George III Guinea was only produced from 1663 to 1814 and was the first English coin to be mechanically minted. The coin is the fifth edition of the King George III Guinea, the Spade Guinea, was only produced between 1787 and 1799. It is the only edition with this portrait of King George and the only one with the Royal Coat of Arms of Great Britain in Scotland on the reverse side. This edition was also the last guinea in circulation, because the sixth edition was reserved as the Military guinea. This edition of the Guinea is unique; This coin is the only guinea in our collection. It was minted in 1793, so it is now over 230 years old. The Gold Guinea is part of Australia’s history; it was the first coin in the list of coins for use in the Australian Colonies, mentioned by Governor King of New South Wales in his Australian Proclamation speech of 1800. The George III Spade Guinea was included in the Limited Edition Sherwood 12 Coin Collection of Notable Coinage of Australia. This coin is the only known guinea coin recovered from the wreck of the Loch Ard. It was already 85 years old when the ship was wrecked.Gold coin; British. 1793, King George III of the United Kingdom of Great Britain and Ireland (1760-1820), Spade Guinea.

Photograph - Digital Photograph, Alan King, Nillumbik Shire Offices, Greensborough, 30 March 2008
Nillumbik Shire Council transferred to the former Diamond Valley Shire Offices in Greensborough after municipal restructuing. The offices became the official Nillumbik Shire Council Offices on 16 October 1995. The former Shire of Diamond Valley Civic Centre or Shire Office building was officially opened on 26th February 1972. Archtiects were A.K. Lines, McFarlane & Marshall and it was built by L.U. Simon Pty Ltd, The Diamond Valley Shire had been created in 1964 from part of the City of Heidelberg. On December 15, 1994 the Shire of Nillumbik was established. Under the Council amalgamations imposed by the Kennett government, the Shire of Eltham, Shire of Diamond Valley and City of Heidelberg ceased to exist with the establishment of Nillumbik Shire Council and the City of Banyule.The new Nillumbik shire surrended the west riding from Eltham to Banyule but in place gained parts of the former Diamond Valley Shire which itself had been created in 1964 from parts of the City of Heidelberg. Three unelected and non-local Commissioners were put in place by the government bringing democracy into question by many members of the local community. The Commissioners determined to abandon the former Shire of Eltham offices located in Main Road, Eltham and in turn occupy the former Shire of Diamond Valley offices located at the boundary of the new shire with Banyule, in Civic Drive, Greensborough. In July 1996 the Commissioners sold the former Eltham Shire Offices and had them bulldozed leading to many years of communiity protest over the process and future development applications. The site has remained vacant ever since. Published: Nillumbik Now and Then / Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p43 It was the need for roads that led to this district’s first council. In 1853 a committee was formed to improve the rough roads, some in Kangaroo Ground being almost impassable in winter.1 The committee fundraised by voluntary levies and grants to improve in particular, the main road between Kangaroo Ground and the Plenty River. From this committee arose the Eltham District Road Board, in 1856, which was the precursor to the Eltham Shire Council. The Board’s first chairman was Kangaroo Ground farmer, John Barr. Secretary was the former committee’s secretary, Andrew Ross, Kangaroo Ground’s first school teacher, and founder of the district newspaper, The Evelyn Observer.2 Most of the board’s income came from a toll-house north of the Lower Plenty Bridge, which funded such projects as a road from Kangaroo Ground to the Caledonia Diggings. In 1871 the Shire of Eltham was proclaimed, with its boundaries the same as those of the Road Board, and Councillor A Donaldson of Kangaroo Ground was the first president. Eltham was at the southern tip of the shire, which extended north to Kinglake and east beyond Yarra Glen. In 1878, part of Kinglake was added to the shire, while the area east of Watts River, near Healesville was removed. In 1912, then again in 1958, the shire was further reduced. Yarra Glen, Steels Creek, Tarrawarra, parts of Healesville and Christmas Hills, were transferred to the Shire of Healesville. In 1972 a smaller area, at Kinglake, was transferred to the Shire of Yea, leaving 277 square kilometres in the Eltham Shire. Perhaps no other Victorian municipality has had so many meeting places. Although from 1858 to 1904, the council convened at the office in the home of Secretary Charles Wingrove, the board, and later the council, also met at other more central locations.3 The board moved from the Fountain of Friendship Hotel to the Eltham Courthouse, to the Kangaroo Ground schoolhouse. It then met at the Kangaroo Ground Hotel, which some considered put it in danger of interruptions by people ‘the worse for liquor’.4 In 1885 the council met at the hall on Mr J Donaldson’s land at Kangaroo Ground. After Wingrove’s retirement, the council rented space at the Kangaroo Ground General Store and Post Office. Then, in 1917, the council bought the former office of The Evelyn Observer, after its printing works transferred to Hurstbridge. In 1934, fire destroyed the shire office, which was temporarily relocated to the Kangaroo Ground home of Shire Secretary, Mr P J McMahon. In 1941, the shire office moved to a new building (which included a public hall) in Eltham, at the corner of Arthur Street and Main Road, where the Eltham Village Shopping Centre was eventually built. Growth required new offices, which opened in 1965, on the former Shillinglaw property in Main Road.5 In 1994, as part of municipal restructuring under the Jeff Kennett Liberal Government, most of the Eltham Shire formed part of the new Shire of Nillumbik. It joined with the north section of the Diamond Valley Shire and parts of the Healesville and Whittlesea municipalities. The Diamond Valley Shire had been created in 1964, from part of the City of Heidelberg. Turbulence followed Nillumbik Shire’s formation. Under the Commissioners the council transferred to the former Diamond Valley Shire offices in Greensborough, and the Eltham council offices were demolished. In March 1997 the first five-member Nillumbik Council was elected. But, in October 1998, the government suspended the council and appointed an administrator . Early in 1999, shire residents voted to increase councillors to nine: comprising five ward councillors and four shire-wide councillors. Elections were held in March 1999. Then, before the March 2002 elections, nine new wards were created.6 In 2008 these were reduced to seven. Today [2008] the council governs a varied population of more than 60,000 people living in townships and on bush properties in the green wedge.This collection of almost 130 photos about places and people within the Shire of Nillumbik, an urban and rural municipality in Melbourne's north, contributes to an understanding of the history of the Shire. Published in 2008 immediately prior to the Black Saturday bushfires of February 7, 2009, it documents sites that were impacted, and in some cases destroyed by the fires. It includes photographs taken especially for the publication, creating a unique time capsule representing the Shire in the early 21st century. It remains the most recent comprehenesive publication devoted to the Shire's history connecting local residents to the past. nillumbik now and then (marshall-king) collection, greensborough, nillumbik shire council offices, civic drive -

R.A.A.F. Long Service Medal
Awarded to Alan Bowers (A236814) who was a R.A.A.F. dental mechanic who serverd during WWII including service in Darwin, and then continued in the R.A.A.F. for some years after the end of WWII The Royal Australian Air Force (and all Commonwealth Air Forces) Long Service and Good Conduct Medal: Awarded to NCOs and ORs of the RAAF (RAF, RCAF etc) for 15 years service. A cupro-nickel plated medal, the obverse features the sovereign's head, the reverse features the crown and eagle emblem of the RAAF (and RAF). 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. The Branch continues to provide excellent service to the ADF community and, despite reduced manpower, will continue to play an important role in Air Force Health operations. http://www.defence.gov.au/health/about/docs/RAAFDental.pdf40cm cupro-nickel plated medal, the obverse features the sovereign's head, the reverse features the crown and eagle emblem of the RAAF (and RAF).
