I've recently acquired a large lot of 500 series factory parts. Every thing you can imagine for 500C, 503 Superwide, and 500 EL to name a few. Gears, assemblies, springs, aux. flaps, screws, many bagged and numbered, some loose, all new from what I can gather. Was owned by an authorized tech in NJ and has been in storage for years since his retirement. Also I have some factory items used to hold the lenses and bodies while repairing, a really nice set of serial numbered spanner wrenches, and a few other tools. Does anyone have any interest in purchasing these or know of anyone who would? I have a couple people I know of, but figured someone on here might have some insight as well. Thousands of pieces. I also have 4 binders of repair manuals from the factory. Thanks!
