The Bolsey B is a 35mm rangefinder camera with a cast aluminium body, introduced by Bolsey in 1947. The lens is a fixed Wollensak Anastigmat 44/3.2 with helical focusing, and the Wollensak leaf shutter gives T, B, 10-200 speeds. The rangefinder is of the split-image type, coupled to the lens but separate from the viewfinder.
