Tool - Grinder, 1960-69
Cooper S.E. Ball Bearing Grinder made and guaranteed by Sunbeam Corporation Limited. Grinders like this example have been made the same since the early 1900s, with this grinder thought to have been produced in the 1960s. It is belt driven, with the other end of the belt being attached to an engine; the same engine that would have powered the overhead shearing equipment in shearing sheds. It was common for shearing teams to bring their own equipment, especially pre-1960 as most shearing sheds were not connected to power, and shearers preferred to work with their own equipment. The engines that powered the shears and grinder were typically fuelled with kerosene or petrol. The large circular disks are attached to the bolt that protrudes from the grinder and fastened tightly with a nut. An example of seeing a similar grinder in action can be found on the following link - https://www.youtube.com/watch?v=O7eimI_Gm9o. Inventor Frederick Wolseley made the world's first commercially successful power-shearing system in Australia in 1888. US company Cooper, which had been founded in 1843 as a maker of sheep dip, began selling Wolseley equipment in the USA in 1895. The Chicago Flexible Shaft Company successfully entered the power-shearing market a few years later and entered a joint venture with Cooper. It set up a branch in Sydney and sold shearing sets, and engines to power them, into the Australian market. In 1921 the US parent company, realising it needed to make products whose sales were not as seasonal as those of shearing equipment, made its first household appliances and branded them Sunbeam. In 1933, changes in exchange rates and taxes led the company to manufacture engines and shearing equipment in Australia via subsidiary Cooper Engineering, which changed its name to Sunbeam in 1946. Although most Australians know of this company as a major manufacturer of household appliances, its rural division flourished and retained the Sunbeam name for shearing equipment even after it was taken over by New Zealand company Tru-Test in 2001. The grinder is formed from a central arch shaped block of green painted metal. Much of this paint has been lost to age, leaving the grinder in a ‘farm used’ condition with much surface oxidation present. On the front of the arch is a specification plate, reading “Cooper S.E. ball bearing grinder. Made and guaranteed by Sunbeam”. At the foot of the arch, three bolt holes are found for securing the grinder to the base of a solid wooden surface. Two of the bolt holes are found on the front of the grinder, with another found on the rear. From the central arch, a bolt protrudes to the right of the grinder. This large bolt is for securing a grinding plate to the grinder. Above the central arch is a pendulum which holds the comb / cutter that is being sharpened. From the pendulum, a large arm extends down (not pictured) to meet and strike the plate spinning at a rapid speed. On the left-hand side of the central arch of the grinder, a wheel is found which a belt is attached to for power. This belt is then attached to a separate engine, spinning the wheel and hence powering the grinder. The wheel is partially covered with a section of protective bent tube, designed to provide protection from the rapidly spinning wheel. Below this wheel is the belt shifter. It is designed to move the protective bent tube from one side of the grinder to the other, to accommodate the grinder in the setup of different shearing sheds. The two separate grinding plates are identical. They have a slight slope for sharpening the comb and cutters in the correct method, with a slight bias towards the base, or “tooth”, of the equipment. The disks have a large central bolt for attaching to the grinder. They have tags on the horizontal axis of the grinding plates, for securing the plates in transportation, and to help with initial alignment when setting up the grinder. The reverse of these grinding plates has the same green painted metal finish found on the grinder. This paint is also in a ‘farm used’ condition, with surface oxidation present. The grinder would be provided from the factory with a comb holder, shifter for securing the grinding plates, emery cloth and emery glue. The emery cloth is what does the actual grinding and is applied to the grinding disks, replacing once well worn. These items can be seen in the final images in the multimedia section, showcasing advertising for this grinder. Plate. Inscribed. “Cooper / S.E.

Functional object - Yarn Spinner and Accessories, John Nesbitt, 19th Century
Nino Corda was a Geelong based textile designer who worked at various textile mills between 1957 & 2003. He travelled the world in search of the latest fashions and techniques and developed timeless designs that were much loved by Australians. These items are on rotational display at the National Wool Museum’s ‘In the Factory’ exhibition. For many years, Nino also worked as part of the Honorary Staff of the National Wool Museum. His passion for the world of textiles provided energy and knowledge to the visitors and staff of the museum. Although Nino has now retired from his honorary position and has hung up his Australian Tartan vest, these items will continue to serve the community in sharing the stories of Australian Textile design.Custom made wooden hinged box with a hook latch.

Functional object - Magnifying Lens, c.1930s
This item was inherited from the donor's father, René Dupuche. John Dupuche, writes: This magnifying glass was used to remove the burrs and thorns that wool-buyers tended to get in their fingers when examining bales of wool. The open end was placed on the finger since the thorn was sometimes buried under the skin. The buyer looked through the magnifying glass and with tweezers or a pin removed the thorn which had rendered the finger inoperative. The wool-buyers needed the sensitivity of their fingers to appraise the suitability of the wool, as buyers had for centuries past, measuring the length of the staple, feeling and counting the crimps in the fibre, its finesse, softness, elasticity and strength, assessing the colour, watching for extraneous matter such as dust or seeds which would not be welcome by manufacturers half-way across the world. Their skills took years to acquire. Knowledgeable buyers were invaluable to their employers, since they were able to evaluate to the last percentage the yield of a bale. My father, René Dupuche, was the ‘principal buyer’ from 1927-1966 in Victoria, South Australia and Tasmania for the international wool company ‘Masurel Fils’ which was one of the largest wool businesses in Europe. It was based in the north of France, in Tourcoing, one of the major wool centres of the world. He was sent to Australia as a young man at the age of 23 and took part in the ‘golden era’ of wool in Australia, and the eventual replacement of hands-on appraisal by ‘core-testing’. Masurel Fils was one of the dozens of French and Belgian firms operating in Australia. These men from Flanders enjoyed a cosmopolitan society augmented by diplomats, European bankers and shipping-line executives for various countries and a handful of scientists and academics.Small black metal magnifying lens with three fold design and two hinges.

Falls Creek Historical Society
Ski Lift Test Ticket 1995
SKI TICKETS Before tows and lifts were introduced at Falls Creek, it could take skiers 20 minutes to climb to the Summit … but only TWO minutes to go back to the bottom. The arrival of tows, then chairlifts and T-bars changed the face of skiing forever. The first rope tow was constructed by Toni St. Elmo for the 1951 winter season. Bob Hymans installed a smaller tow for his guests at Skyline Lodge. Tows were still quite slow, so in 1956 Bob Hymans created his single chairlift. In 1958 the Village rope tow, designed by Albury engineer Jock Wilson, opened. It was financed by shareholders including Bill Griffith (Bowna Ski Club) and the Bridgford family (St. Trinian’s Ski Club). Several other tows followed including the Summit T-bar in 1961, built by Ron McCallum and operated by Alpine Developments Pty. Ltd. which was a company formed by C. H. (Bill) Bridgford. By 1982 Falls Creek was served by 16 different lifts or T-bars, all owned and operated by Alpine Developments (Holdings) Pty. Ltd. During the development of Falls Creek, different methods have been used to pay for the use of tows, lifts and T-bars … including metal tokens, single tickets, strips of tickets and season passes. The Falls Creek Historical Society Collection includes many examples of these items.This ticket is significant because they represent a stage in the progression of chair lifts and management at Falls Creek Tourist Village.A test ticket produced prior to the full run of tickets being created for the 1995 season.falls creek passes, falls creek ski lifts, falls creek tourism -

Forests Commission Retired Personnel Association (FCRPA)
Delayed Action Incendiary Device (DAID), Bryant and May - Richmond, Large double ended match
The Forests Commission developed the use of helicopters for aerial ignition from the mid 1960s. Bryant and May at Richmond worked with the Commission to develop a Delayed Action Incendiary Device. DAIDs as the were known, had an overall length of 180 mm, striker end length - 10 mm. Ignition end length - 80 mm, then a layer of high melting point wax (to prevent accidental ignition when rubbing together in transit). Both ends coated with a modified match head compound with safety fuse exposed length between coated match ends. There was a 17-second delay from when the small end was struck to an intense flaming of the large end, which lasted for 40 seconds. DAIDs were dangerous so were stored in a metal box outside the helicopter along with a disposable striker patch attached with a quick release pin to a special half-door. The first test was with a Bell 47G on 4 October 1967 and the first use, anywhere in the world, of DAIDs to backburn a large bushfire was undertaken in north eastern Victoria in February 1968. There was a crash of an FCV helicopter conducting aerial ignition near Wandiligong on 19 April 1978 with the tragic death of two forest officers and their pilot. The crash led to the immediate end of the use of DAIDs and the adoption of the safer Premo ping-pong ball incendiary machine which originally came from Canada but was modified at the Altona workshops. Overall, the development of aerial ignition techniques by the Forests Commission from the mid-1960s resulted in a steady climb in the area burnt each year…. peaking at 477,000 ha in 1980-81 and with an impressive 10-year rolling average of 220,000 ha around the time of 1983 Ash Wednesday Bushfires.Developed in Victoria for aerial ignitionLarge double ended match used for aerial ignition and back burning by dropping from a helicopterbushfire, forests commission victoria (fcv) -
