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. NORMALLY NUMBER OF GRATICULE SCALE DIVISIONS PER RADIAN (K) X LENGTH OF TAIL IN FEET (I) = 12X 105. IN OTHER CASES MULTIPLY GRATICULE READINGS BY 1.2/KI BEFORE CALCULATION ON RULE" Top of Slide Rule - RAAF Ident No G268/480 Serial WG/22pilot balloon slide rule, raaf

This poster, published by the State Parliamentary Recruiting Committee, depicts Lieutenant Albert JACKA, VC, as a role model for a huge campaign to enlist sportsmen into the Australian Imperial Force in 1917. Jacka achieved instant fame back home when he became the first Australian to win the Victoria Cross during the First World War. It was said that one of the reasons he was such a good soldier, and had such a fighting attitude, was that he had been a boxer before the war. The campaign to enlist sportsmen was fuelled by a strong belief that by playing sport young men developed specific skills and qualities that could be used on the battlefield.Representative of two common recruiting devices used in Australia, a well-known local soldier and a target number of men required for a specially named group.Depicts Lieutenant Albert Jacka, VC, as a role model for a huge campaign to enlist sportsmen.

A prayer wheel is used in Tibetan Buddhism for personal worship. Tibetans believe that spinning the prayer wheel which as thousands or millions of mantras inside is equal to saying that many mantras, while being done in a fraction of the time. This helps accumulate merits, purify negative karma and obstacles on the path to enlightenment. This wheel has a hollow metal cylinder attached to a rod handle, made of ivory (with carved elephants), inlaid with coral and turquoise. Inside the cylinder is a tightly wound scroll printed with numerous mantras and wrapped around a spindle. The cylinder is embossed and decorated with inlaid coral and turquoise. A chain with a small weight at the end (made out of copper alloy) is affixed to the cylinder, allowing it to be spun by a slight rotation of the wrist. tibetan buddhism, holy objects, worship devices

Willcox and Gibbs: Serial No. 158679.|The Willcox& Gibbs Sewing Machine Company was founded in 1857 by James E. A. Gibbs and James Willcox and opened its London Office in 1859 at 135 Regent Street .
