It's not an advance in design if the photographer has to wind the film on and then cock the shutter is separate operations. That's true... but maybe there was the intent that A was mechanically linked to the movement of the advance lever... engaged to B that cocked the shutter....??? Welcome, dear visitor!

However the advantage of the lever operating the aperture is that the aperture information is transferred to the viewfinder display mechanically by A and B. Seeing the aperture in the viewfinder would be an innovation for a rangefinder camera and the sort of thing prototypes are built to test. And I think you are overlooking there seems to be no other way to control the aperture on the lens apart from the lever.

willeica Posted January 21, 2021 Share #43 Posted January 21, 2021 From Jim Lager, received just now. "This piece was undoubtedly buried in the Leitz Wetzlar Museum contents . When I photographed items there in 1988 I did not see this item. I suspect the curved lever may have been a way to cock the bladed shutter independent of the film winding lever at the camera top. Only Leitz knows and there may be nobody left to tell us the story. " William 2 Quote Link to post Share on other sites More sharing options...

Published in my „PROTOTYPE LEICA“ book, pages 363; 370-375. An idea of using the Leicaflex body, for a RF camera. Something from the 1960s, which re-appeared around 1980, when Peter Loseries created the „M6 ELECTRONIC“ on basis of the R4. From the pictures I think(!), that it is the very same camera, maybe pictures taken at Leitz Wetzlar or Leica Solms Museum, time ago. my very best LARS NETOPIL Greetings Lars! Good to have your knowledge base here on the forum! 2 Quote Link to post Share on other sites More sharing options...

pippy Posted January 22, 2021 Share #46 Posted January 22, 2021 There was something about the overall look and shape of the prototype which reminded me strongly of another, more recent, camera and I've just remembered which one; https://www.kenrockwell.com/zeiss/ikon.htm Philip.
