Jeanette Perkins was born in 1927 at Ballarat. She attended Alfredton State School and Pleasant Street State School before completing her secondary schooling at Ballarat High School (BHS). During her later years at BHS Perkins decided that she wanted to become a geologist, but was ineligible for university when she failed Leaving Certificate maths. She attended an interview with the principal (Heseltine) at the Ballarat School of Mines (SMB) and announced that she wanted to be a geologist. Heseltine was, according to Perkins, aghast: he informed her that there had never been a female geologist at SMB and they didn't want one. But Perkins persisted. Only then did Heseltine reluctantly enrol her in the School's Applied Chemistry Course which offered the most geological subjects, moreover, it was the only one he considered available to a 'mere' female. After graduating Perkins was employed as a metallurgical chemist with M.B. Johns Valves, Ballarat. In 1949 she married Alfred Watson. In 1951 Jeanette and Alf Watson moved to Melbourne where she commenced work as a metallurgical chemist at the Maribyrnong Ordnance Factory while studying geology part time: Alf returned to study at the University of Melbourne. Once again, Watson set a precedent by becoming the first female student to study geology part-time at the Melbourne Technical College. Increasing demands brought about by her growing family, she turned to part-time lecturing second and third year stratigraphy and palaeontology at RMIT. In 1957 the Watsons moved to the Mary Kathleen Uranium Mine in NW Queensland where he was appointed electrical design engineer. After their return to Melbourne in 1960, Jeanette taught herself to SCUBA dive and quickly developed a passion for the sport and the marine environment. She taught senior science to secondary students for 10 years whilst working towards a Masters degree. In 1991 Jeanette Watson was awarded a Doctorate from Deakin University.women of note, ballarat school of mines, alfredton state school, pleasant street state school, ballarat high school, leaving certificate maths, interview with principal, heseltine, geologist, applied chemistry course, no female geologists, metallurgical chemist, married 1949, melbourne, ordinance factory, part time study, melbourne technical college, rmit, part time lecturer, scuba diving, science teacher for ten years, masters degree, doctorate, deakin university

In 1941, the scientific instrument manufacturing firms of  Henry Hughes & Son Ltd, London, England, and  Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.

Navigators use parallel rule with maps and charts for plotting a specific course on a chart. One long edge is used with the compass rose on the chart, aligning the centre of the rose with the desired direction around the edge of the rose. The compass bars are then ‘walked’ in and out across the map to the desired location so that lines can be plotted to represent the direction to be travelled.

This model parallel map ruler is a good example of the commercial diversity of navigational instruments made by Kelvin & Hughes after World War II. It was made in numbers for use by shipping after the second world war and is not particularly rare or significant for it's type. Also it was made no earlier than 1947 as the firms of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd who took over from Smith & Sons were not amalgamated until 1947. It can therefor be assumed that this ruler was made during the company's transitional period to Kelvin & Hughes from Smith Industries Ltd.Brass parallel rule in wooden box with blue felt lining.Rule inscribed on front "Kelvin & Hughes Ltd" " Made in Great Britain"flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, parallel rule, kelvin & hughes ltd, map ruler, plot direction, navigation, maps, echo sounder, kelvin & james white, lord kelvin, baron kelvin of largs, scientific instrument

The Micro-Professor I Plus (MPF-IP) was a low cost, versatile microcomputer system featuring sophisticated software and hardware capabilities. (MPF-IP) boasted a display panel with the ability to display 20 characters using 16-segment fonts. All 64 standard ASCII characters could be displayed. The operation of the MPF-IP was controlled by an 8k monitor program which resides in the Read Only Memory (ROM). The monitor, aided by 4k Random Access Memory (RAM), enabled the user to enter a comprehensive set of single keystroke commands, making it easier for the user to use the CPU, memory and I/0 devices. This allowed the user to concentrate of microprocessor software development and application design. The system allowed printing at 48 lines per minute, and the ability to permanently record the commands, data, programs, status and other messaged. Each character printed by the printer is in a 5 by 7 dot matrix. Although the prime purpose of the programming was for machine language object code formed as hexadecimal numbers, the Micro-Professor has an embedded Tiny Basic interpreter for which formation of some of the alpha characters using a standard 7 segment display was ingenious. The program memory consisted of non volatile 2 kilobytes electrically programmable ROM whilst the Random Access Memory came with 2 kilobytes of static RAM but could be upgraded to 4 kilobytes by insertion of another chip. The entire memory space of 64 kilobytes was accessible by way of the terminals on the left hand side of the board. Engineering and Science students from the Ballarat School of Mines and the Ballarat College of Advanced Education used a class set (as they were relatively inexpensive at approx. $100 each) during the mid to late 1980s. Student were encouraged to borrow the Micro-Professors in order to assist in learning how to use them. Only one was ever not returned on time. When pressed to return the device the student confessed that his dog had chewed the plastic case. This is still in our collection complete with bite marks! The Micro-Professor used a Zilog Z80 microprocessor. This was the most powerful of the 8 bit microprocessors at the time. Zilog was derived from the Intel 8080 microprocessor. The Z80 had 158 instructions of which the Intel 78 instructions were a subset. The Intel processor continued on through development in the IBM computers as 8086, 80286, 80386, 80486 and later the pentiums. Zilog lost most of its market share when it developed the 16 bit Z8000 microprocessor. Although the microprocessor was excellent, the lack of peripherals caused users to abandon Zilog products.

The design of this and other similar treadle powered dental engine (or dentist drill) was in common use by dentists from the 1870’s into the 1920's. When electricity became accessible to most communities the electrically powered dental engines began to take over from the treadle power. Over the ages teeth were extracted using picks and scissors and other gouging instruments. Bow drills, hand drills and even a "bur thimble" drill were later used to prepare cavities for filling. Some drills were made bendable by attaching flexible shanks between the metal bur and the handle, giving access to the teeth at the back of the mouth. Other mechanical devices were introduced along the way, such as clockwork drills, but they were hard to handle and inefficient. Over the centuries “dentistry has been performed by priests, monks and other healers. This was followed by barbers; the barber’s chair may well have been the precursor to the dental chair. “(SA Medical Heritage Society Inc.) In 1871 James Morrison patented the first commercially manufactured 'foot treadle dental engine', the first practica dental engine although others had been introduced as early as 1790 (by John Greenwood). Handmade steel burs or drills were introduced for dental handpieces, taking advantage of the significant increase in the speed of the drill. In 1891 the first machine-made steel burs were in use. The treadle drill reduced the time to prepare a cavity from hours to less than ten minutes. In 1876 the Samuel S. White Catalogue of Dentist Instruments listed a 12 ½ inch wheel diameter dental engine, with 14 bright steel parts, for sale at US $55 In today’s market, this is the equivalent to US $1200 approx. The specifications of that dental engine are very similar to the this one in our Flagstaff Hill Maritime Village’s collection. It is interesting to note that workings of a similar treadle dentist drill were used and modified to power a treadle spinning wheel of one of the volunteer spinners at Flagstaff Hill Maritime Village. The foot treadle dental engine was a milestone in dental history. “Historic importance of treadle powered machines; they made use of human power in an optimal way” (Lowtech Magazine “Short history of early pedal powered machines”) The invention of a machine to speed up the process of excavation of a tooth lead to the invention of new burs and drills for the handpieces, improving speed and the surgical process of dentistry. They were the fore-runner of today’s electrically powered dental engines. This treadle-powered dentist drill, or dentist engine, is made of iron and steel and provides power for a mechanical dental hand-piece that would be fitted with a dental tool. The drill has a three footed cast iron base, one foot being longer than the other two. A vertical C shaped frame is joined into the centre of the base, holding an axle that has a driving-wheel (or flywheel) and connecting to a crank. A slender, shoulder height post, made from telescoping pipes, joins into the top of this frame and is height adjusted by a hand tightened screw with a round knob. On the post just above the frame is a short metal, horizontal bar (to hold the hand-piece when it is not in use). A narrow tubular arm is attached to the top of the stand at a right angle and can move up and down. At the end of the arm is a firmly fixed, flexible rubber hose protected for a short distance by a sheath of thin metal. At the end of the hose there is a fitting where the drill’s hand-piece would be attached; a small, silver coloured alligator clip is also at the end. A treadle, or foot pedal, is hinged to the heel to the long foot of the base, and joined at the toe to the crank that turns the driving-wheel. There is a spring under the toe of the treadle. The metal driving-wheel has a wide rim. Touching the inside of the rim are four tubular rings that bulge towards the outside of the driving-wheel, away from the pole, and all meet at the hub of the axle. The axle is bulbous between the inside of the driving-wheel and the frame then passes through the frame and is attached on the other side. The driving-wheel has a groove around which a belt would sit. The belt would also fit around a pulley on the arm, at the top of the post. The pulley is joined to a rod inside the arm and this spins the drill's hand-piece and dental tool holder. The two shorter feet of the base are made from a long metal bar that has been curved outwards, and its centre is bolted to the base of the pole. Under the ends of the curved legs of the base are wedge shaped feet. The driving-wheel is decorated in light coloured paint on both sides, each side having three sets of floral decals evenly spaced around them, and each about a sixth of the wheel's circumference. Similar decoration is along the sides of the frame. The foot pedal has decorative cutout patterns in the centre of the foot and at the toe. On the long foot of the stand is some lettering with a fine, light coloured border around it. The lettering is hard to read, being a dark colour and flaking off. There are also remnants of fine, light coloured flourishes. The foot pedal has lettering of the maker’s trade mark cast into the metal at the ball of the foot. Lettering on the base is peeling and difficult to read. The foot pedal has a trade mark cast into it that looks like a combination of ‘C’ , ‘S’ , ‘A’, ‘R’. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, dentist, teeth, dental drill, dental engine, treadle drill, foot powered drill, treadle engine, orthodontics, dental surgery, james morrison

The design of this and other similar treadle powered dental engine (or dentist drill) was in common use by dentists from the 1870’s into the 1920's. When electricity became accessible to most communities the electrically powered dental engines began to take over from the treadle power. Over the ages teeth were extracted using picks and scissors and other gouging instruments. Bow drills, hand drills and even a "bur thimble" drill were later used to prepare cavities for filling. Some drills were made bendable by attaching flexible shanks between the metal bur and the handle, giving access to the teeth at the back of the mouth. Other mechanical devices were introduced along the way, such as clockwork drills, but they were hard to handle and inefficient. Over the centuries “dentistry has been performed by priests, monks and other healers. This was followed by barbers; the barber’s chair may well have been the precursor to the dental chair. “(SA Medical Heritage Society Inc.) In 1871 James Morrison patented the first commercially manufactured 'foot treadle dental engine', the first practica dental engine although others had been introduced as early as 1790 (by John Greenwood). Handmade steel burs or drills were introduced for dental handpieces, taking advantage of the significant increase in the speed of the drill. In 1891 the first machine-made steel burs were in use. The treadle drill reduced the time to prepare a cavity from hours to less than ten minutes. In 1876 the Samuel S. White Catalogue of Dentist Instruments listed a 12 ½ inch wheel diameter dental engine, with 14 bright steel parts, for sale at US $55 In today’s market, this is the equivalent to US $1200 approx. The specifications of that dental engine are very similar to the this one in our Flagstaff Hill Maritime Village’s collection.

On the foot is painted lettering naming it "The Brentfield" and there is a fine line of light coloured paint creating a border around the name. The paint under the lettering is peeling off. The drill has a Y-shaped, three footed cast iron base, one foot being longer than the other two. A vertical frame is joined into the centre of the base, holding an axle that has a driving-wheel (or flywheel) and connecting to a crank.

On the post just above the frame is a short metal, horizontal bar (to hold the hand-piece when it is not in use). A narrow tubular arm is attached to the top of the stand at a right angle and can move up, down and around. There is a pulley each side of the joint of the arm and a short way along the arm is fitted a short metal pipe. A little further along the arm a frayed-ended cord hangs down from a hole. At the end of the arm is another pulley and a joint from which hangs a long, thin metal pipe with two pulleys and a fitting on the end. A treadle, or foot pedal, is joined to the long foot of the base, and joined at the toe to the crank that turns the driving-wheel. The metal driving-wheel has a wide rim.

It took 15 years to invent the can. It took 100 more to invent a standard way to open it. In the 19th century, decades after the invention of canning, there were virtually no can openers. Canned food, such as sardines, came with its own "key" to peel back the tin lid. Birth of the can One of the oddest things about the can opener is that the can predates it by almost 150 years. Though common today, cans were once military-grade technology. In 1795, Napoleon, to whom the phrase "an army marches on its stomach" is attributed, offered 12,000 francs to anyone who could find a way to preserve food. Without any knowledge of bacteria or their role in food spoilage, scientists didn't even know where to begin. It took 15 years before a chef named Nicholas Appert claimed the prize after successfully jarring food. Soon after that, his countryman Philippe de Girard came up with a variant on Appert's method—metal tins—and sold the idea to the British. Spoiled food, and the sickness it caused, was a widespread problem. The public would have benefited from canned food, but for decades cans were almost exclusively for the army and the navy. The canning process, with its hours of boiling and steaming, its scrupulous cleanliness, its heated metal, and its need for a great deal of disposable material, made canned food far too expensive for anyone but the military. No can openers were needed or even possible. The metal of early cans was too thick to make openers practical. Soldiers and sailors had plenty of sharp objects on hand and made ample use of them when they wanted to eat. During the 19th century, the process of canning was refined and mechanised, and the metal wall of the average can slimmed down enough that a civilian could get it open—if that civilian had the right tool. No one had that tool yet, so early cans had to open themselves. In other words, they came with built-in openers. The result was a confusing but pleasing free-for-all, in terms of product engineering. Each type of food came with its own kind of can, and each kind of can came with its own kind of opener. Tinned fish and meat were often sold in rectangular cans. These cans were fitted with a "key" that would roll down the top of the can. Coffee, beans, and other types of meat were packaged in cylinders with metal strips that could be peeled back with their own kinds of built-in keys. Cans of milk, which didn't need to be completely opened, came with puncture devices. As tinned food became more common, its containers became more regular. A nice cylindrical can became the norm, and, as these cans filled kitchens, more engineers put their minds to finding a convenient way to open all of them. The first standalone can opener worked on a simple principle: point, stab, and pull. From the mid-19th century to the end of World War I, the typical can opener looked roughly like a wrench, if the lower 'jaw' of the wrench were replaced with a blade. People used the blade to puncture the top of the can near its edge, push the upper jaw against the side of the can, and drag the blade through the metal along the rim. Because meat was the first and most popular canned substance, these can openers were often shaped to look like cows and given the nickname 'bully beef can openers'. The bully beef can opener, popular in the mid-19th century, resulted in many lost fingers. Later, a corkscrew was added that was seated in the handle, and could be pulled out for use. Bully beef can openers were so common, effective, and sturdy that they are still frequently available on collectors' sites. Some are advertised as “still working,” and every last one of them is, without a doubt, soaked in the blood of our ancestors. Dragging a sharp blade along the edge of a can is certain to cause injury sooner or later. So once people got a reliable can shape and a reliable way to get the can open, the search was on for a reliable way to get a can open without the possibility of losing a finger. The answer came in 1925, from the Star Can Opener Company of San Francisco. This is probably the first can opener that resembles the one people have in their kitchens today. Instead of using a blade to pry open a metal can, buyers could clamp the edge of the can between two wheels and twist the handle of one of the wheels to move the blade around the lip. The Star can openers weren't perfect. Compared to the bully beef model, they were flimsy and breakable, but they probably prevented a few injuries. Six short years after the Star model came to market, the first electric can opener was invented. It was patented in 1931 by the Bunker Clancey Company of Kansas City, who had already been sued by the Star Can Opener Company for trying sell a double-wheeled can opener like the Star model (the case was dismissed). The electric can opener must have seemed like the wave of the future and a sure-fire seller, but it proved to be too far ahead of its time. In 1931 not that many households had electricity, and those that did weren't interested in buying can openers. The Bunker Clancey Company was subsequently bought by the Rival Company, which still makes small appliances like can openers today. It took another 25 years for electrically powered can openers to become practical. In the 1950s, Walter Hess Bodle and his daughter, Elizabeth Bodle, developed an electric can opener in the family garage. Walter came up with the opener's blades and motor, and Elizabeth sculpted the outside. Their can opener was a free-standing unit that could sit on the kitchen counter. The Udico brand of the Union Die Casting Company put it on the market in time for Christmas in 1956 and had great success with it. Over the next few years it came out in different styles and colours, and, like the bully beef can opener, has become a collector's item. Also like the bully beef model, Udico can openers often still work. They don't make 'em like they used to. Although there have been some design changes and refinements over the last sixty years, there have yet to be any more leaps forward in can opener technology. If you're resentfully opening a can, you are almost certainly doing it using the Star design, manually forcing the can between two wheels, or the Bodle design, clamping the can into a free-standing electrical opener. Whether or not you enjoy your holiday meals, at least you can be happy that you are not getting poisoned by your own food or cutting open your hand with the blade you use to get at it.

Kempthorne Lighting Pty. was established as Coffey Lanterns in East Malvern, Melbourne Victoria in 1931 by brothers Selwyn and Owen Coffey. They manufactured lighting fixtures and fittings including oil lamps for marine use as well as for the domestic market. In early 1936 two other brothers, Erle and Terence had joined the company which was renamed Kempthorne Lantern Works Pty., Ltd. In 1946 Kempthorne joined with a small design team who had developed a domestic fan to form the subsidiary, Mistral fans. The company previously known as Kempthorne Holding Ltd was listed on the stock exchange in 1968. In 1977-1979 Kempthorne Mistral Ltd. Was a holding company comprising of Kempthorne Lighting Pty., Ltd. & Mistral Fans Pty., Ltd.

Kelvin Company History: The origins of the company lie in the highly successful, if strictly informal, the relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, who was an optical instrument maker in Glasgow in 1850. He was involved in supplying and mending apparatus for Thomson's university laboratory and working with him on experimental constructions. White was actually declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson's laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson's design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company). Thomson, who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death in 1884, raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd . Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd . Hughes Company History: Henry Hughes & Sons was founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as Henry Hughes & Sons Ltd in 1903. In 1923, the company produced its first recording echo sounder and in 1935, a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing Marine Instruments Ltd. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd., Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military use. This model compass is a good example of the commercial type of instruments made by Kelvin & Hughes after the world war 2, it was made in numbers for use on various types of shipping after the second world war and is not particularly rare or significant for it's type. Also it was made no earlier than 1947 as the firms of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd who took over from Smith & Sons were not amalgamated until 1947. Given that Smith and Sons is engraved on the compass with Kelvin & Hughes it can be assumed that this compass was made during the company's transitional period to Kelvin & Hughes.Compass, marine or ship's card compass, gimble mounted, with inscriptions.

Sport and available playing areas were important and every effort was made to provide this for the students when they moved into the new building in 1921. The terraces leading down from the gaol wall were terraced and clearing areas of rubble to provide playing areas for football and cricket was done by the students. In November 1922, a tennis court was opened in the Battery Paddock. It was designed by Syd Chambers and constructed by Les Waller, former students of the Ballarat School of Mines. A new tennis court was built and opened in 1934, in the same area. This photograph is of the 1938 Tennis Team - Ballarat Junior Technical School. The boys standing are L to R: D. Eltringham and J.
