The Reflex Box is an SLR camera made by KW from 1933. It was KW's effort to present a true SLR in the style of a common box camera. It is very similar in form to the horizontally-oriented model of the Ensign Roll Film Reflex, of about 1925, but whereas the Ensign has only a 'T' and 'I' shutter, the Reflex Box has three instantaneous speeds.
