And now for something a little different. Years ago, for no good reason, I replaced the lens on this Argus (what model was it?) with a Krauss of Paris Zeiss Tessar in a helical focusing mount. Its flange was a nice fit on the camera and a little tape across the film aperture allowed a new focusing mark to be set. No use posting a picture from it as it looks like any one taken with a good Tessar. Bet you don't have one of these Dan!
