[Reviving a 2014 thread] Another detail that stuck out was the 60mm lens.
First, it's missing the NASA P/N and S/N which is engraved into the base of the lens.
Second, NASA shifted to a silver focus ring and lever for Apollo 12 forward that allowed for more accurate focal judgement. This lens doesn't have it. Here you'll see the updated ring and "paddle" design.
Third, the serial number of the lens 5198329 is slightly higher than an MK70 lens I own that I can date to June 1972. There are red markings on the back of each lens that give you the month of and year of manufacture. That dates this lens to later than June 1972. Apollo 15 flew in '71.
What I think happened was the previous owner took an early 60mm Hasselblad MK70 lens and added those painted levers (the real ones aren't painted - they're blackened) or added a replica lens, a few of which were made from spare parts to help promote Hasselblad.
