Winfried's best guess is dead right, of course. The latching of the shutter is not interlinked with the relase button. There is a "wind-lock" of course but that is not the essence of the enquiry here. There is a small bias spring ( a wire loop spring) on one of the shutter activator-ring pins. It's only a very light bias and its purpose is to prevent the shutter blades opening during the cocking stroke. My best guess is that such little spring is dislodged. This would account for the shutter opening during the film advance lever-wind stroke (when there is a film in the camera). My qualification about the need for a film in place is because it is the rotation of the film sprockets which actually cock the shutter. But I digress. Paul - Access to the shutter mechanism is through the front end - but Vito B's came in many incarnations and just about every one of them differed in construction to the extent that there is no universal stripdown procedure to get into the actual shutter mechanism. The commonalities are that the iris is to the front of the shutter and the actual shutter blades are the rearmost components as can be seen through the film-plane. You might fall into the common trap of stripping apart the immediate front end including the iris mechnism whereas in fact the iris components and front element group come off as a complete module. The Prontor SVS model also requires a custom-made tool to release the brass ring in front of the shutter cam-plate. You could proceed on a "suck it and see" basis - but some of the Vito B models are easily wrecked. You might want instead to entrust the camera to someone who is familiar and experienced with whatever your particular model. Hope this helps . a bit. Stuart Willis |
