This is the only 6x9 SLR in Japan. This SLR have a vertical traveled focal plane shutter with T, B,1/20-1/500 second. The Luminant brand lenses with focal length of 90-400mm were available The dark room works was required, because the original roll film holder had a reverse winding mechanism to maintain flatness of the film (This description was foud in Westa's web site, but I found the dark room is not required during the film exchange.)

Rittreck SP. a later model of this camera, had slower shutter speeds (the slowest was 1/2 second).
