Minolta Pocket Autopak Camera with a Pocket Flash 110 attached and cover.Three pieces in total. It was made 1978 with a 26mm (f3.5) zone focusing (1.6 feet to infinity) lens. Electronic shutter with speeds of 2 seconds - 1/1000. CDS meter provides programmed exposure control. Hot shoe. Tripod and cable release sockets. Built-in close-up lens and detachable flash. Viewfinder shows a red warning LED if a flash is needed. With the f:3.5 lens, a flash with a guide number of only 40 (in feet, at ISO 100) will be good to over 20 feet with ISO 400 film. The camera senses when a flash unit is mounted, and automatically sets smaller apertures for focus distances of 12' or less, to prevent . overexposure, assuming a fixed-output flash with a guide number of 40.

After years of precursory surveying, debate and proposals the most ambitious civil engineering project of the day, the Overland Telegraph Line, began construction in September 1870. Superintendent of Telegraphs, Sir Charles Todd led the construction through “terra incognita,” guided by the precursory surveys of John McDowall Stuart and technologies such as his prismatic surveying compass. The unknown and hostile landscape claimed the lives of several men and scores of transport animals in the dogged pursuit of telegraphic connection to the rest of the world. Completed in August 1872, the Line connected Australia to the world via telegraph wires running 3,200 kilometres from Port Augusta in South Australia, to Darwin, then connecting via submarine cable to Java and beyond. The “earth [had been] girdled with a magic chain” according to the then Governor of New South Wales, Sir Hercules Robinson. How does it work? For use in surveying, the sight vane and prism are turned up on their hinge and the instrument is held horizontally either in the palm of one's hand or on a tripod. Two small discs of red and green glass attached to the prism can be flipped down over the sight line to reduce glare. The objective is to bring the subject into the sightline created by the prism, aligning with the thread of the sight-vane until the subject is bisected evenly. Once aligned, the division on the card may be read through the prism. This reading provides the magnetic azimuth, used for calculating the bearings of distant landmarks. Circular instrument mounted in a brass case with glass window and brass lid. The compass card face four black compass points printed on mint green paper; on the underside the magnetic needle would be affixed, all held in place by a brass knob at the centre. The arched labels of "Sawtell" and "Adelaide" and the Prince of Wales feathers appear to have been affixed with adhesive which has since yellowed in the areas of application on the compass card. The compass face is printed with numbers, every 10 degrees from 10 - 360, printed in reverse indicating this compass would have once held a mirror at the sighting bracket. On one side of the brass case is a brass hinged sighting-prism, possibly of ebonite. The sighting-prism is mounted in a hinged brass bracket on one edge of the brass case. It has two flip-type filter glasses (red and green) and folds down into a retracted travelling position. A hinged brass bracket on the opposite edge would have held the sighting bracket - carrying the sighting vane and mirror - which is now missing or removed. Under the hinge is a lever, possibly related to the movement of the bracket. Underneath the brass case is an indented circle with screw threads, possibly for attachment to a tripod, and indistinguishable marks scratched into the surface.Etched on to the centre of the lid, "Sawtell ADELAIDE / No 792."

The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. This instrument was used as a training aid to help teach surveyors at the Royal Australian Survey Corps School of Military Survey.

Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.

The Plane Table Alidade was used as the sighting Instrument in the production of historical manual hand drawn maps. A Plane Table Board mounted on a tripod is levelled and the Alidade is placed on the table with the vanes perpendicular to the it. Each sighting vane has a central thread lined up on the target and the angle to that target point is then drawn on the map sheet using the beveled fiducial edge. Plane Table Surveying is used as a quick method where less accuracy is required or needed. Plane table Surveying is a relatively portable and inexpensive method and was used extensively before the advent of sophisticated surveying instruments. The photo at 6489.2 is an Australian Army Survey Corps Party using a Plane Table Alidade in Syria during WWII.

A Plane Table consists of a smooth wooden table surface (with metal strengthening supports) mounted on a sturdy base. The base, a three-legged Tripod, is designed to support the table over a specific point on land. The connection between the tabletop and the adjustable Tripod legs permits the user to level the table precisely, using bubble levels in a horizontal plane regardless of the roughness of the terrain. The Plane Table is a surveying device used in surveying and mapping to provide a level surface on which to make drawings, charts or maps. An alidade, with or without a telescope located on the tabletop is used to sight features and draw angles to that feature. Using these lines to the same feature from different setup locations it is possible to locate that feature on the map. Plane Tabeling was widely used by the early members of the Australian Survey Corps and in both World Wars. It remains a simple and effective tool to teach the fundamentals of mapping and surveying. It was simple to use and was reasonably robust and portable. See also item 6489.2 for the Plane Table Alidade.A wooden Plane Table with alloy fittings to strengthen and support the table top.
