I have a Voigtländer Bessa produced around 1935. This model has the shutter release on the door and the finder without cover. It seems impossible for me to trigger the shutter without causing massive camera shake. I can't use a shutter release cable as the strut gets in the way. My shutter is the simplest model with two speeds: 25 and 75 plus T and B. The lens is Voigtar 1:7.7 F=10.5 cm. The body and the bellows are in a very good condition and it is a shame I can't use the camera. Any ideas?
