Prismatic binoculars with extending sun shades and a leather carrying strap. Each eyepiece is independently adjustable and has a choice of three filters (yellow, grey, green) that can be deployed by means of levers on each tube. The sun shades are of a diaphragm type that was patented by Barr & Stroud in 1934. The maker's name, the government broad arrow, and patent information are all inscribed on the body of the binoculars.
