The Supar first appeared around 1933. It was a cheap general purpose anastigmat for camera and enlarger use. Around 1945 the lens was re-calculated and issued in different focal lengths. By that time it would not have been used on cameras. The lens had a black mount with aluminium iris ring. Later a satin chrome mount was used. Coating was added in the late 1940s and click stops were available on some lenses. By the late 1950s Wray advertised this lens as being the most popular enlarging lens. Two versions were produced with f3.5 or f4.5 aperture.
