A sailmaker's hook is also called a sail hook, bench hook, stretching hook or third hand. It is used to hold the canvas of a sail or similar object while pulling tight with the left hand. This ensures the canvas is tight while stitching, keeping the sewn seam straight. This tool is still in use today wherever a canvas sail requires stitching. it's design has not changed since it was invented centuries ago as a sailor's third hand, helping to keep canvas sails taught during edge stitching or repairs.Hook; sailmaker's bench hook. Metal rod with a hook at one end and a flat head at the other end. This tool would be used in conjunction with a brass swivel and a lanyard.warrnambool, shipwreck coast, flagstaff hill, flagstaff hill maritime museum, flagstaff hill maritime village, sailmaker's hook, sail hook, bench hook, stretching hook, third hand, sailmaker's tool, sailmaking, canvas sewing, maritime trade, sailmaker

This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

Manufactured in the 1960s, this mobile emergency telephone exchange was fitted into a caravan. Part of the Shepparton Division State Disaster Plan, the caravan could be towed to areas affected by disasters to enable communications to recommence. The caravan remained in service until approximately 1974.Mobile infrastructure plays an important role in Australian communications, owing to the often remote and hostile environments in which Australians live and work. Exchanges such as this facilitated phone calls in the aftermath of an emergency, particularly for hospitals, police and other emergency services. Today, Mobile Exchange on Wheels (MEOWs), Cell on Wheels (CoW) and Satellite Cell on Wheels (SatCOW) - which provide temporary landline and broadband services, mobile phone coverage and service in areas without communications infrastructure respectively - are a critical part of emergency response procedures for natural disasters such as fire and flood. Though technology has progressed, the need for rapid service in remote areas remains a present concern of the communications service providers in Australia. This mobile service infrastructure is historically significant as an early example of a service which has evolved over decades, yet is still needed today. The exchange, as a representative example of a vehicle which would provide early-response in a disaster, is socially significant as a facilitator of critical communications needs in devastated communities: access to emergency services and contact with family and friends. The exchange itself, intact from its period of use, provides an insight into technology of the 1970s.Mobile emergency exchange housed in a caravan trailer on 2 wheel base, duralin body, steel tow bar, Caravan divided into 3 sections; the exchange room; the relay room and the main frame room.

Hugo Wertheim (1854-1919), was a merchant and manufacturer and was born on the 12th July 1854 at Lispenhausen, in the German electorate of Hesse-Kassel, son of Meyer Wertheim and his wife Minna, née Heinemann. Hugo reached Melbourne in October 1875. He soon began advertising, from premises at 39 Flinders Lane East, as agent for his father's cousin Joseph Wertheim, a well-established manufacturer of sewing machines. Hugo returned to Germany where he married Joseph Wertheim's daughter Sophie Emilie (1864-1953) on 30 August 1885 at Frankfurt. the couple then came to Melbourne. In a short time, with extensive advertising, Hugo established a substantial business, selling sewing machines, bicycles, pianos and other mechanical devices, under brands such as Wertheim, Electra, Planet, Griffin and Hapsburg. He also mounted elaborate displays at agricultural shows and in 1901 at the Pan American Exposition, Buffalo, United States of America. O. C. Beale worked with him before setting up his own piano business in New South Wales. Hugo continued to own 25 per cent of one of Beale's companies, which became Wertheim's Queensland business. In 1908 Wertheim opened a large, innovative piano factory at Richmond, Melbourne, intending to produce 2000 pianos and player pianos annually, predominantly using Australian materials. In laying the foundation stone, Prime Minister Alfred Deakin observed that “few men with such opportunities for a life of ease would have embarked on such an enterprise” Hugo died of chronic hepatitis on 11 July 1919 at his home at South Yarra, his wife, two daughters and three sons survived him; Herbert Joseph (1886-1972), the eldest, continued the business. Rupert became a share broker and went on to represent Victoria in inter-State tennis in 1913-27 and Australia in Davis Cup matches against Czechoslovakia in 1922. The piano factory closed in 1935, becoming a Heinz food processing plant and in 1955, GTV Channel 9 studios and offices.Early Australians had to be self-reliant in regards to making and mending their clothes and utensils. This sewing machine was one of many items used that exhibit the skill and craftsmanship of the women in these early families. A sewing machine was a necessary part of each home and this item demonstrates how women of the time managed had to become self-reliant in the repair and making of their families clothes to make their household budgets go further.Sewing machine, Wertheim brand “ Syst 182” hand crank operated machine with folding handle, timber case and carry handle.
