The collection documents his joining the Australian Imperial Expeditionary Force A.A.M.C. Dental Reserve, his subsequent discharge and post military employment in the Town of Warrnambool as a Hackney Carriage Driver and later as a second class engine driver.. This collection gives examples of references and certificates of leave required to join the A.I.F. in 1916. The discharge certificate is a good example of what was given to military personnel after their services were no longer required. The llicense and certificate of competency show some of Charles' post war endeavours. Charles is listed on the Warrnambool Fire Brigade World War 1 Honour Roll as an active member.

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).

Decorative object - Peacock, Minton Majolica life-size model, Paul Comolera, artist, Designed: c. 1873; Made: c. 1875
... with a practice in Collins Street, and his wife, a dental mechanic, had... in Collins Street, and his wife, a dental mechanic, had purchased ...This majestic peacock embodies the technical achievement, skill and ingenuity of artisans during the 19th century. It is now known as the 'Loch Ard Peacock' and was designed and modelled in 1873 by Paul Comolera (1818-1897) and fired in one piece at the Minton factory at Stoke-on-Trent in the United Kingdom in 1875. The peacock has been portrayed in symbolic motifs and has figured heavily in folktales and fables since antiquity, and many cultures around the world see it as a symbol of beauty, rebirth and power. Wealthy Victorians loved majolica, and the large peacock would have been the ultimate home accessory as a conservatory ornament – combining their desire for nature, the exotic and vibrant colours. The peacock model was listed in catalogues by Minton & Co. for a retail price of 35 guineas or sold as a pair for 90 guineas. Minton & Co. was founded in 1793 by Thomas Minton (1765–1836) and became a famous pottery and porcelain manufacturer. Comolera was a French artist and sculptor, renowned for dramatic naturalistic forms and life-size renditions of birds and animals that won him admiration in public and artistic circles. He was employed by Minton & Co. from 1873 to 1880, and the life-sized peacock became his best-known work. Comolera kept a live peacock loaned from the nearby Duke of Sutherland's Trentham Hall Estate in his studio to create a life-size model of fine buff earthenware model, which was then hand painted in brilliantly coloured green and blue glazes to mimic the peafowl’s dazzling plumage. There are no surviving production records, but according to documents in the Minton Archive, nine peacocks were made by Comolera. However, today, some historians now believe that twelve were fired at the Minton factory; research is ongoing. These peacocks were so admired that Minton & Co. used them as exhibition showpieces at International Exhibitions in London, Paris, and the United States of America, ensuring the company had a worldwide reputation. So, when Melbourne hosted an International Exposition in 1880, Minton & Co. sent out ceramics and tiles, and in particular, this peacock was intended to be part of their exhibit in the British Court in the Exhibition Building, built in the Carlton Gardens. The early dispatch date (1878) indicates that the company may have intended to exhibit their wares, including the peacock, at the 1879 Sydney International Exhibition, but the company did not take up this option. The ship that Minton & Co. used to bring the peacock and their other wares to the Australian colonies was the ill-fated Loch Ard, which sunk after striking Mutton Bird Island near Port Campbell, Victoria, in calm foggy weather in June 1878 on the final leg of the ship's journey to Melbourne. The loss of 52 lives made it one of Victoria’s worst shipwrecks. Therefore, this peacock never made it to the grand exposition in Melbourne, as Minton & Co. had planned. Charles McGillivray dragged this peacock, still in its original packing case, onto the beach in the gorge just two days after the Loch Ard went down. The peacock was rescued unscathed apart from a chip on its beak (only repaired in 1988). After a disagreement with a Melbourne Customs Officer, Joseph Daish, McGillivray stopped his salvage operations, leaving the peacock on the beach. The second salvagers were James Miller and Thomas Keys. Miller was a member of the firm Howarth, Miller and Matthews, Geelong, who had brought the salvage rights to the Loch Ard wreck on 10 June. When Miller and Keys arrived at the wreck site, a storm had washed many of the salvaged goods, including this peacoc,k back into the sea. The two men found the peacock in its case ‘bobbing along in the water’ and pulled it back to the beach. To ensure the peacock wasn't washed out to sea again, Miller and Keys hauled the packing case containing the peacock up the gorge's cliff face to the top, ready to be transported. In an interview in 1928, Keys claimed that at the time of the rescue, the head had broken from the body. This account was proven to be true in 1988, following the birds' display in Brisbane. This peacock began its life in Australia, not in the grandeur of an International Exhibition as intended, but in the hallway of a simple domestic house in Geelong. It appears Minton & Co. did not attempt to buy this peacock back. Florence Miller, daughter of James Miller (Loch Ard salvage rights holder), later remarked that the only item of real value rescued from the wreck had been the peacock and that this had been kept by her father in the family home at Malvern for many years and became a treasured family possession. As such, this 'Loch Ard peacock' was almost forgotten and mistaken with other Minton peacocks around the world. Miss Florence Miller tried to sell the peacock due to financial difficulties in the 1930s but was unsuccessful. While attempting to sell her Loch Ard relic, it was displayed in the window of the old Argus newspaper office, which was at 76 Collins Street, Melbourne; the Argus had relocated to the corner of Elizabeth and La Trobe Streets in 1926. Between 1935 and 1939, the old Argus building was occupied by the Joshua N. McClelland Print Room, which sold not only paintings and prints but also antiques and authentic replicas, as well as hosting exhibitions. Miss Florence Miller loaned her peacock for display at the Victorian Historical Exhibition held in the National Gallery on 1st June 1935, the 57th anniversary of the Loch Ard wreck. As a result, the peacock attracted public attention in books, newspapers and magazine articles that told the story of its survival from a shipwreck. Miss Florence Miller was keen to sell the peacock, even writing overseas to Captain Blain on November 30th, 1938, about the possibility of a sale, but this became no longer possible due to the outbreak of war. Recent information points to the Loch Ard peacock being owned by John S R Heath before its sale to Frank Ridley-Lee in May 1941. Research is ongoing, but it seems likely that John Samuel Robert Heath, a leading Melbourne dentist with a practice in Collins Street, and his wife, a dental mechanic, had purchased Miss Miller’s Loch Ard peacock before its sale in 1941. They were lovers of fine arts, music, wine and food. The peacock in the window of the old Argus building could have attracted their attention as they had already purchased the old stone Presbyterian Church on Warrigal Road, Oakleigh, in 1933 and had converted its interior. The home, renamed The Studio, even included Melbourne’s first all-electric kitchen. The peacock was perfect for display in the Studio’s entrance. A magazine article published after the conversion was completed included photographs of the interior. The picture of the ‘portico’ had a caption below that stated, “Some of her [Mrs Heath’s] finest pottery was salvaged from the Loch Ard Wreck”. In 2025, Heath’s two remaining sons remember running around in the entrance with the peacock standing there, oblivious to its value. Heath was an accomplished artist, studying under Max Meldrum. He painted and exhibited his works at The Studio and in a public exhibition, and he was a finalist eight times in the coveted Archibald Prize portrait competition, including the submission of his self-portrait that is now part of his grandson’s collection. The next owner of the Loch Ard Peacock was Frank Ridley-Lee. He displayed it at his home in Ivanhoe after buying it at an auction in May 1941. The peacock remained in the hands of the Ridley-Lee family until it was offered for sale by auction in 1975 as part of an art collection belonging to Mrs Ridley-Lee's estate. The peacock was not sold at this time, as the reserve price of $4500 was not met. This news was passed on to the board of the newly created Flagstaff Hill Maritime Village. Urgent efforts were made to collect the necessary money through fundraising by the Warrnambool City Council and public donations. The Fletcher Jones Company and the Victorian Government contributed half the cost. On 9 September 1975, the Loch Ard peacock was purchased by Flagstaff Hill Maritime Village, and it found a new home at the maritime museum. Since then, it has only left Warrnambool twice. Firstly, in 1980, at the centenary celebrations of the Royal Exhibition Building in Melbourne, and secondly, in 1988, the peacock was given pride of place at the entrance to the Victorian Pavilion at the Brisbane World Expo, acknowledging that this Minton Majolica peacock is the most significant shipwreck object in Australia. The Minton majolica peacock is considered of historical social and aesthetic significance to Victoria and is one of only a few 'objects' registered on the Victorian Heritage Register (H 2132), as it is a most notable and rare object associated with the Minton factory of the 1870s and works by the celebrated sculptor Paul Comolera along with the wreck of the Loch Ard on the Victorian coastline. This Minton peacock is historically significant for its rarity; it was one of only 9-12 known to exist. The shipwreck of the Loch Ard is also of significance for Victoria and is registered on the Victorian Heritage Register Ref (S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulation of artefacts from this notable Victorian shipwreck. The collections object is to also give us a snapshot into history so we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's early social and historical themes. The collection is historically significant is that it is associated, unfortunately with the worst and best-known shipwreck in Victoria's history. The peacock, resplendent in polychrome glaze, stands perched on a rocky plinth decorated with vines, leaves, flowers, blackberries and wild mushrooms. The peacock’s breast is cobalt blue; the wings and legs are in naturalistic colours. The tail is a mass of feathers coloured in green, ochre blue and brown — a fantastic display of artistry and Minton expertise.

Bolt Cutter, 1878
Cyrus Chambers was a self-described mechanic who started out winding bobbins in his father's woollen mill and went on to invent machines that changed their industries. Cyrus Chambers came from Quaker parents the ninth of thirteen siblings, he once said a year before his death. “I believe I have succeeded because, first, I was industrious; second, because I made a study of the subject that was before me.” At age 7, Chambers went to work in his father’s mill. His job was to monitor bobbins—wooden spindles around which thread was wound and to remove and replace them as they became full. "There was no child labour law at that time," he later recalled. Chambers loved machinery and always regarded himself as a mechanic rather than an inventor. At age 16, Chambers was sent to learn dentistry with an older brother, (Edwin) who was already in the field and willing to take him on as an apprentice. Chambers was talented at working with small parts. He used his brother's dental instruments to build a miniature high-pressure steam engine of silver. It ran at 3,000 revolutions per minute and weighed less than a half-ounce. At that time it was the smallest engine that had ever been constructed. The engine was displayed at the 1876 Centennial and is now in a permanent collection at the Franklin Institute USA. Chambers major invention was the paper folding machine and came from reading that school teachers made less than the young girls who were employed to fold book pages as they came off the press. He told friends that his first efforts were to make the machine that would fold newspapers after demonstrating his device he met with Horace Greeley of the New York Tribune who advised Chambers would never invent the machine that would be able to fold his newspaper or books. In less than a year Chambers had built a full-size machine capable of folding large newspapers and books and was installed at J B Lippincott & Co folding pages for the "Comly Speller" this machine ran successfully for twenty-five years until the printing works burnt down. Chambers then went into partnership with a brother and they established the firm "Chambers, Brother & Co" at a plant in Philadelphia. It was also observed in 1910 and a fact that there was not a periodical or newspaper printed or recently published book that had not gone through one of Chambers inventions. Chambers went on to produce many mechanical inventions and improvements to existing tools and machinery most notable was his invention for the machine that would make clay bricks. This machine made forty bricks per hour and by the end of Chambers life after many improvements, it could make more than four hundred. Although there were a large number of bold cutters made of this patent at Cyrus Chamber’s foundry in Philadelphia, the item is associated with a notable American inventor of the nineteenth century. This particular patent for a bolt and rivet cutter won Chambers the prestigious Elliott Cresson Medal. This cutter is just one of the many inventions and mechanical improvements that Cyrus Chambers made during his lifetime, contributing to the ongoing development of mechanical improvements that were occurring in American industry of the time and therefore a notable addition to the Flagstaff collection.Cast iron bolt cutter with removable tempered steel cutter.
