After a recent basement cleaning I dug up an old Pentax MX SLR camera (from the 70's I think ??). It's not in the best shape but the only non-superficial wear seems to be that the film advance lever only moves about a half inch. Other than that I think it just needs a clean and it could be fully functional again. Pentax has stopped servicing these cams and my next step is to go by the local Wolf shop and see if they have any ideas. Does anyone know anything about old cameras and repairs? or where to get them repaired? I would at least like to get an estimate to see if it's worth fixing. thanks.
