hi
i have this same camera ( maybe ) , it belonged to my grandparents ..
can you post a photograph of what you are talking about ?
mine is a vest camera ( the bed folds out and the lens slides out on a track
there is a shutter release on the shutter ( lever ) and a cable release socket ...
is it the lever on the shutter ?
did the shutter release unscrew ?
if it is the shutter, you might have to buy another shuttered lens
and swap it out ( take the back off hte camera and unscrew the
retaining flange ) or take the shutter to a repair guy to have him remove
the face plate and re-attach ? machine a new part? the lever ...
sorry for my apparent cluelessness about what it is that is broken ..
great camera btw !
i use mine with paper negatives
