Opera Glasses came into existence as a result of a long line of inventions, and further improvements upon those inventions. The process started in the year 1608 when a Dutch optician by the name of Hans Lipperhey developed the first pair of binoculars with a magnification capability of X3. Less than a year later, a well-known inventor and philosopher by the name of Galileo developed what became known as the Galilean telescope. Advertisements were first found for opera glasses and theatre binoculars in London as early as 1730 in the form of a long collapsible telescope. The "Opera Glass" as it was referred to; was often covered in enamel, gems, ivory, or other art and paintings. For almost 100 years opera glasses existed merely as telescopes. In Vienna, in 1823 the first binocular opera glasses and theatre binoculars began to appear. They were two simple Galilean telescopes with a bridge in the centre, each telescope focused independently from the other by extending or shortening the telescope until the desired focus was achieved, which was useful, yet very cumbersome. Two years later in Paris, Pierre Lemiere improved on this design and created a centre focus wheel. This allowed the focusing of both telescopes together. After this development, opera glasses and theatre binoculars grew in popularity because of the superior view they facilitated in opera and theatre houses. The beautiful design of the glasses themselves also added appeal to the opera-going crowd. By the 1850's opera glasses and theatre, glasses had become a must-have fashion accessory for all opera and theatregoers. A vintage pair of 1920s opera glasses probably made in France by an unknown maker the item is significant due to it's provenance that can be traced and it's completeness as a useful social item and fashion accessory used by theatergoers from the mid 19th century and well into the 20th century. Some people still use modern variants of theater glasses today to improve their enjoyment of the theater.Both glasses and case are covered with black and white snake skin.

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.

Testing of eye conditions requires the services of eye specialists, who often had to travel around a wide area. This kit is incomplete, but demonstrates how optometrists needed a wide variety of instruments to diagnose sight conditions. Although incomplete, it also contains a booklet for the Standard Testing Set 1H-1 produced by the same company (Keeler) and briefly describes some of the instruments in the case.1 maroon case with two blue velour inserts'Note this side up' in Dymo tape on outside.assessments, keeler optical products
