I shoot with these. I would just take a look at the shutter curtain, I wouldn't wind anything unless I was prepared to buy. Take the film pack holder off and look at the cloth. It is a rubberized material, if it seems smooth and flat and still flexible (as best as you can tell) then the camera probably can be made operational fairly easily. If the curtain seems dry and cracked, then I would walk away unless you want more of a project.
