Hi, I'm new to this forum and desperate to find a solution to a problem. I want a Rollei pistol grip for one of my 3003 cameras, the grip serial no is SL-2000 and too date have been unable to find out how the grip trigger fires the shutter and from web searches there seem to be about six different versions of the same product none showing the firing mechanism. Is there anyone on this forum who might be able to help please? The Rollei Club Forum seems to be unable to register new members so I can't ask them, sorry if this seems cheeky but I love these cameras but at 71 I just can't hold them for long and the hand strap is if no help either. Many thanks Paul.
