I am not a specialist, so I am only noting what I have observed. Please understand that the descriptions of evaluations, etc., are my personal opinions. I have not tested the camera with film loaded. If we meet in person, I will confirm the described operations. However, if shipping is involved, I request that all transactions be "no claims and no returns" under any circumstances. Please also be aware that I will use recycled materials for shipping.

[TTL Finder/No. TL14551] ・I confirmed the linkage between the TTL finder and the body, and the shutter speed appears to be changing as set. (This is a subjective judgment as I have not used measuring equipment.) ・The TTL finder displays an exposure value that is about 2 stops over. (Compared with the reflected light metering value of a Minolta Autometer.) ・There is no corrosion in the battery chamber.
