I'm messing around with a Ricoh 300 that I picked up recently. (You can see it in my avatar.) The lens was literally about to fall off of the camera, because several screws were missing inside. This led to the shutter leaves (is that the right term?) coming loose and just flopping around in there in front of the iris. Fortunately, none of them actually slipped out through the wide open lens. Unfortunately some of them got, well, bent. One even has an impression from one screw head or another. It isn't a huge deal, because I bought the camera intending to take it apart with my son and see if we could put it back together--at least what of it that there was. This was the first one I've ever gone into. Now I'm a little bugged to get it back together right. Are these little screws so custom that I pretty much have to use another 300 as the donor, or how widely is worth checking? Other Ricohs of similar vintage? Other Japanese? Other anything? At the very least I'd like to come up with enough screws to hold this together so it can be a shelf queen. Right now it can only lie prone! In any case, it has been fun and given me some confidence.
