Wray London had a patent for a special penta prism slr since 1947. But the stage from drawings to production obviously must have been hard, as their first and only PP SLR was produced in 1959 and discontinued in 1961. They did present an slr in 1950,
produced from 1951, but with a reduced prism that turned the image sideways and gave a frame of 24x32. The name was Wrayflex 1. Then followed Wrayflex 1a in 1953, the only visible difference being the film counter going to 36 frames, not 44, but giving a normal
24x36 frame. A flash shoe came in 1954, and finally the true penta prism camera Wrayflex II in 1959.
But during the 10 years of production, only some 2 800 cameras were produced. So, despite a promising start with an impressing patent, the English
contribution to the PP SLR history was rather short, and not at all shining.
