The Wrayflex was the only successful British 35mm single lens reflex camera. As Morley relates the origins of the camera are not clear with the most likely contenders being designers Harry and Werner Goebbels, former workers in the German camera industry, being supported by Commander M E P Studdart who brought the brothers to Britain.
Wray patented a 35mm. single lens reflex camera on 20 May 1948 (British patent numbers 656548 and 656595). These patents included a pentaprism, spring motor wind and through-the-lens metering. None of these features appeared on the eventual production model. British patent number 698409 of 13 July 1950 described more closely the Wrayflex camera that was actually produced and announced at the British Industries Fair the same year and launched in 1951. The Wrayflex II was introduced in 1959 with pentaprism viewing. A series of Wrayflex lenses designed by the former Taylor, Taylor and Hobson lens designer Professor Charles Gorrie Wynne who joined Wray in 1942 was produced.
In total around 2800 units were produced over a nine year period.
