This type of kit was used by the Regiment for vehicular cross country navigation. The crew commander would stand in front of the vehicle with a prismatic compass and guide the driver to align the vehicle on the back bearing of the required direction of travel. The discs were set for time of day and the required bearing and the driver would watch the compass and steer so that the shadow of the gnome was on the arrow. The compass would be re-set about every half hour to adjust for rotation of the Earth. In featureless country navigation was by dead reckoning by direction travelled by compass and distance travelled from the vehicle odometer. Armoured vehicles are now equipped with GPS navigation aids rendering the sun compass obsolete Type of equipment used by the Regiment on exercisesMetal construction. One fixed and one rotatable aluminium disc with a vertical steel gnome at the centre. The lower disc is marked with bearings in mils, the upper with time of day. There is a rotatable aluminium arrow under the 2 discs. A 33 mm dia spirit level is fixed to the top disc.On spirit level "GENERAL #847"daytime use only, navigation aid

An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly. The Club played a significant role in the establishment of the small airport at Marlo and in the ongoing operation and development of the airport over the years particularly for patient transfer by aerial ambulance.

The ‘Resumatic’ brand, British made, lightweight device comprises a red pulley with attached length of white rope and harness. Information on the item indicates that it was the property of the Department of Transport, Australia. The Commonwealth Lighthouse Service was associated with the Department of Shipping and Transport in 1951 and the Navigational Aids Branch of the Department of Transport in 1972 so the harness may date to this period. The easily operated descent device was used for automatic, controlled descents from overhead structures, such as towers and other buildings and did not require a power source or tools. The user needed to make sure the unit is secured to an anchor point so that the cable could be dropped to the ground. As soon as it was secured the user could put on the support harness, step off the edge and travel down to safety. The device complements a number of other items of rescue equipment held in the wider Parks Victoria lightstation collection which attest to the dangers inherent in lightstation work and necessity for first aid kits, resuscitators, life buoys, life jackets and other devices such as harnesses and pulleys used for moving people. These include a bosun’s chair and harness with pulley, Royal Flying Doctor first aid cabinet, resuscitator kit and case, first aid kit, lifebuoy and cork fragments x 4 all in the Gabo Island collection; a rescue basket, resuscitation kit and case, and pulleys and ropes at Cape Otway; rescue stretcher made of bamboo at Wilsons Promontory; and a rescue anchor at Cape Schanck. The Cape Nelson rescue harness, although unique in the broader lightstation collection, is a relatively common device that is still manufactured more or less the same in England. It has second level contributory significance for offering insights into the various methods used in rescue operations by Victoria’s lightstations.Length of white rope attached to a harness and a red pully device.yes

A foghorn is a device that uses sound to warn of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used with marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rocky outcrops, shoals, headlands, or other dangers to shipping. An early form of fog signal was to use a bell, gong, explosive signal or firing a cannon to alert shipping. From the early 20th century an improved device called the diaphone was used in place of these other devices, The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides, the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, this air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would be repeated. This method of producing a low audible sound was further developed as a fog signal by John Northey of Toronto and these diaphones were powered by compressed air produced by an electric motor or other mechanical means that admitted extremely powerful low-frequency notes. The example in the Flagstaff collection is an early cased and portable diaphone used on pleasure or sailing craft. By manually turning the crank handle air is produced and fed into valves that direct air across vibrating metal reeds to produce the required sound. in foggy weather, fog horns are used to pinpoint a vessels position and to indicate how the vessel is sailing in foggy conditions. One blast, when sailing on starboard tack and two blasts, when sailing on a port tack and three dots, when with wind is behind the vessel. Since the automation of lighthouses became common in the 1960s and 1970s, most older foghorn marine installations have been removed to avoid the need to run the complex machinery associated with them, and have been replaced with an electrically powered diaphragm or compressed air horns. The example in the collection is significant as it was used in the early 19th century for sailing vessels was important but these portable crank fog horns have also been superseded by modern electric varieties. Therefore the item has a historical connection with sailing and maritime pursuits from our past.English Rotary Norwegian Pattern nautical foghorn within a boxed pine varnished case with exposed corner dovetailing, original leather carrying strap, brass side crank, and original copper trumped horn.

This book is a 19th Century treatise on aids to navigation. It belonged to John Cowtan who held land near the Cassady's Bridge area in Caramut Road today (he was related to the Cassady family) and who is mainly important in the history of Port Fairy. Captain John Cowtan was a ship's master for John Griffiths and a Launceston entrepreneur and ship owner between 1839 and 1844. In 1847 he went into partnership with John Bland, establishing a merchant's business with riverside buildings at the Port Fairy wharf. He left Port Fairy in the 1860s. The date of John Cowtan's signature in this book is 1849 (certainly a very early one in our history) and inside the front cover he has written notes about the local weather, mainly as it affected sailing conditions in late 1849 and early 1850. These notes are of great historical interestThis book is of great interest because it belonged to a Port Fairy historical figure and because of the hand written weather notes inside the front cover. This is a hard covered,leather bound book of 680 pages. It contains printed text, illustrations, tables, maps and sketches.One page is torn Some pages are stained. .

The Mark II Pilot Balloon Slide Rule was made of wood laminated with heavy white plastic with a length of 24.5-in. and width of 2.5 inches. Mark II rules were manufactured in Australia by W & G (Melbourne). The W & G rule differs only slightly from the English A. G. Thornton LTD rule. The W & G rule uses serif fonts and has some fiducial marks that the English rule lacks. Exact dates of production are not known but the MK II is known to have started production by 1927. The printed scales are engraved in the plastic faces. The slide rule has 4 captive cursors (glass windows and brass guides) that ride in slots on the top and bottom edges. Each can be moved independently of one another. The cursors are missing from this item. Brass knobs at both ends of the slide facilitate its movement. The case is fabric covered wood with felt lining. No known history for this item as located in a property after purchase. The Pilot Balloon slide rule is used to convert the observed azimuth and elevation readings into wind velocity and direction records. The use of slide rules was abandoned with the wide spread adoption of computers and programs to do the calculations, as well as the decline in the use of optical pilot balloon theodolites.Made in Australia by White & Gillespie (Melb) Pty Ltd. Established in 1910, the firm was involved mainly in printing plate manufacture, but during the Second World War it manufactured a variety of navigational aids and range finding devices for the military. About 250,000 instruments were made during that period. After the war the company produced, among other items, drawing instruments and slide rules. The case is fabric covered wood with felt fabric lining containing a long black laminate ruler with numerous white markings and numbers. Top of the ruler is in three sections with the centre section movable by small gold metal knobs at either end. This slide rule contains a engraved notation on the rear face "IMPORTANT.
