Barr & Stroud 7 x 50 Naval Binoculars 1930s/40s
Barr and Stroud collaborated in 1888 on a naval rangefinder. They eventually formed a company in 1913 and in the 1930s won the contract to supply naval binoculars. The pair shown is seen on many war films, and is a pattern fitted with extendible "ray shields", a lens hood, here seen extended. There are three internal filters operated by thumb levers under the prism housings. These are yellow, neutral density and dark green. These must also be a late pair, as they are fitted with valve nipples to pump nitrogen into the binoculars as a better seal.
This type of binocular was, with the Canadian REL, a Bausch & Lomb design manufactured under license, the standard lookout binocular. Mind, in 'The Cruel Sea', a pair of Barr & Strouds transform themselves into Canadia REL binos when Jack Hawkins climbs down from the bridge with the former and, by the time he's reached the bottom of the ladder, they have become RELs!
A smaller version identical, but 7 x 42 was used by Fleet Air Arm observers.
