A very unusual set of opera or field glasses. They are Sterling silver and leather, hallmarked for London 1902. The makers mark is partially worn off but the retailer is stamped on the other side, A Barrett & Sons 63 & 64 Picadilly. This set of binoculars is disguised as a chatelaine purse, complete with a ring on a chain for hanging from your chatelaine. There is a small push button on the bottom that opens the "purse" to reveal the lenses. Another knob, on the side, turns the lenses so you can see through them. The focus is near the top. They measure approx. 4 1/2" by 3 1/2". In good working order. The only condition issue is on one side near the top, the leather has ripped. Please see all photos. Ingenious, and stylish too! . Guaranteed to be as described.
