5 rewind knobs and some rewind knob parts, screws, etc in a plastic sack. I don't know what they fit, but you may find them workable on different kinds of cameras. $5 plus the cost of shipping (which will probably be something like $2 in the USA).
I've shown you 2 views of the same sack.
PayPal ok for international, check/cash/money order for USA buyers, please.
