When I made the cam for my 6", I was able to use a cam from a 150 (6" is 152.4mm) without any peening. I've often wondered if Goerz N.Y. used the drawings from Berlin and called a 150 6 inches and close enough. Anyway, I had only to remove a small amount of metal from the cam to make it match - I shimmed the shutter on the board until I had infinity using the existing stop on the camera for the 150, then filed the cam. The only tools were a file, a loupe, and a magical marker. If the 150 the camera came cammed for is exactly 150, and the Dagor is exactly 6", I should have had to peen the cam slightly near the end. But then who knows what the exact fl of the lens the cam came from was, and how that body's rangefinder was - STIV cams are matched to the lens and body.
