George Reed was a draftsman who lived in Bentleigh , City of Moorabbin in mid 20th C and used this pencil for his work. Eversharp is an American brand of writing implements founded by Charles Rood Keeran in 1913 and marketed by Keeran & Co., based in Chicago. Keeran commercialised Eversharp mechanical pencils (manufactured by two companies, Heath and Wahl) then expanding to fountain pens when the company was acquired by the Wahl Adding Machine Co. in 1916 and it was named "Wahl-Eversharp". In 1941 the company renamed itself, this time as Eversharp. The company continued until 1957 when it was acquired by Parker Pen, which continued to use the Eversharp brand for a time. In 1993 Parker was purchased by the Gillette Company, which already owned the 'Paper Mate' brand - the best-selling disposable ballpoint pen. In 2000 Gillette sold its writing instruments division to the company Newell Rubbermaid, USA, and In 2011 the Parker factory at Newhaven, East Sussex, England, was closed, and its production transferred to Nantes, France.An 'Eversharp' propelling pencil manufactured prior to to the development of the ball point penA gold plated propelling pencil c1941engraved : G. .

Long term loan from Neurological Society of Australasia Museum of Neurosurgical Instruments , South Australia Catalogue with Historical Commentaries Second Edition January 2006 Copy located at RACS MuseumSTUART MORSON'S MECHANICAL INJECTOR FOR ANGIOGRAPHY. Stuart Morson(1913 - 1980) of Sydney had this injector constructed in or before 1952. It is said that it was not used much. The injector embodies two 10 ml and two 20 ml Record syringes coupled to a single delivery system. Each is operated by a piston. The pistons are driven from cylinders drilled in a metal block within the casing of the injector; the motive power must have been hydraulic or pneumatic pressure delivered through a manifold with taps allowing each syringe to be worked in isolation. The casing also contains two linked micro switches operated from a distance; it is unclear what was the role of these switches, and it is possible that a component of the unit is lost. JB Curtisl stated that a mechanical injector was devised in 1949 for serial angiography by his collaborator Schuster, but was not felt to be safe enough for use. For many years, neurosurgeons and neuroradiologists preferred to inject by hand.

An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually several capsules, stacked to add up their movements) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. This type of barometer is common in homes and in recreational boats. It is also used in meteorology, mostly in barographs and as a pressure instrument in radiosondes.5 inch Aneroid barometer on wooden basebarometer, aneroid

The knitting machine is a recently designed instrument, especially when it is compared with its ancient counterpart, the loom. It enables the creation of many metres of fabric very quickly. A knitting machine is composed of a series of needles which mimic the process of manual knitting. The mechanism engages numerous mechanical elements simultaneously and enables the creation of many metres of fabric very quickly. In addition, a knitting machine can be setup to produce unique bolts of fabric. The density of the fabric may be modified and a knitting machine can produce double-faced effects. A doubled-faced effect creates colour combinations through the introduction of an additional colour to the knitting pattern. This knitting machine is a Coppo brand. It contains over five hundred needles and was produced in the 1960s. It is a representation of the best available in the world at that time. Originating from Italy, it was designed for commercial use. Through both precision and capacity, Italian artisans were seen to be the best in the world of textiles and knitwear. Through emigration, globalisation and the regularly available quantities of wool, Australia came to compete on this stage. The owner of this particular machine migrated from Italy in 1959. When she did, she brought with her a Dubied knitting machine. She later replaced it with this Coppo. When in Australia the owner began work as a piece worker, knitting jumpers and worked for some of the iconic names in the Australian knitting trade including ES Poratt and Alpin Manufacturing. The owner’s role progressed from a piece worker to a wool garment designer and she won many Wool Industry Awards in the 1970s and 1980s. Her high quality of work using and her individual custom designs were spoken about by many of her customers and she had a very large private clientele. She designed and knitted fully fashioned tailored jumpers for people for around 30 years.Knitting table sits on a stand with wide metal legs. Legs contain lettering 'COPPO torino'. Legs are connected via three thin metal poles as well as a metal band and the bed of knitting table at top. The connecting metal band has the lettering 'SUPER - COPTAL' attached. The Knitting table itself contains two beds and a bench at the rear. Attached to the bench is a thin metal structure for the elevation of yarn. It has four crane esk structures above on this metal structure. The bench is covered in a pale grey laminate in the imitation of wood.

The clock parts were discovered in 1980 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. 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 and 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. This group of brass clockwork parts is incomplete. The pieces were in the ocean for over 100 years before Julie recovered them from the Loch Ard wreck. Their size would suit the works of a carriage clock, with a mainspring and weight to power the clock movement, a pendulum to measure the clock's speed, arbours, posts, pillars and at least one other plate. They would have been mounted inside a protective case with a small door to easily access the clock face for setting the time and accessing the key's winding hole. The clock cases were usually made from decorative gilt brass with a glass front and a carrying handle. The parts include a weighted second hand with a decorative four-pronged finish at one end, a rounded weight at the other, and a hole for attaching it to the clock face. The gear teeth profiles are ‘cycloidal’, an arch shape with vertical sides, which is common for antique clocks. Modern clockworks have ‘involute’ teeth with sloping sides and a squared-off top. The brass carriage clock parts are an example of a mechanical clock produced in the 1870s. The clock's design is a part of the chain of technological improvements in methods for timekeeping. Its cycloidal gear teeth were the forerunner of the more modern involute gears. The group of clock parts includes a weighted hand or arm for signifying the seconds. This feature was uncommon in portable Victorian-era clocks. The clock parts are also significant for their association with the ill-fated sailing ship Loch Ard, wrecked in 1878. The travelling clock or officer’s clock may have been part of the cargo destined for the 1880 Melbourne Exhibition, or the personal possession of one of the people on board the vessel. Brass clockwork parts from a mechanical clock, sixteen pieces. Parts comprise a plate, large gears or wheels, small pinions or wheels with fine teeth, wheels with cogs, and a weighted second hand. The parts were from a carriage clock ca. 1878. They were recovered from the wreck of the sailing ship Loch Ard.flagstaff hill maritime museum and village, warrnambool, great ocean road, shipwreck coast, loch ard, wreck of the loch ard, 1878, mutton bird island, peterborough, scuba diver, 1980s, shipwreck artefact, relic, clock, mechanical, clock parts, time, timekeeper, horology, chronometry, cogs, time keeping device, scientific instrument, chronometer, john harrison, longitude, carriage clock, coach clock, portable clock, travelling clock, travel clock, traveller’s clock, officer’s clock, weighted second hand, victorian era, cycloidal gear teeth, brass clock, julie wilkins
