Yes, already cleaned and ready for this weekend's tryout.
The first two pics are the inside of the top lens/mirror area. All cleaned up, mirror super nice, lenses were very nice in and out, and viewing screen is impeccable. I really think it is not worth fiddling anymore with it for now, as it seems all is good (other than the erratic self-timer issue). Seems someone had cleaned the camera before and forgot a strand of cotton in there on the mirror bracket.
Third pic is with the mirror in place, thus why you see the upper lens and its mirror image...
All in all, I had my doubts, but VERY happy as soon as received. The seller was not very familiarized with the camera, had not tested it, replied to all of my emails with questions and what to look for, but for the price, it would've made a great display piece if damaged.
