I am selling an Olympus OM-1 MD body. All functions work (shutter speeds, self timer, etc.). I tested the TTL light meter with a 1.45 V battery and the readings are approximately correct. The camera requires the MRB625 battery (1.3 V) for accurate readings however (these are widely available, but I do not have one handy at the moment). The light seals could use updating as with most older SLR's. There are no signs of damage, but cosmetically there are signs of use. I 3-D printed a replacement motor drive coupler cover -- sorry about the green color, but it works fine.
Sold as shown with a body cap that I think is aftermarket, but it does the job.
