You have found a vintage Minolta SR-T Super (or SR-T 102) from the 1970's.
The previous owner said that it works, but I have no way to test it.
-The shutter release button clicks.
-The film advance lever advances the film (as shown in the status window).
-The rewind knob retracts the film (I found that out because there was a roll of film in the camera).
The camera comes with the original MC ROKKOR-PG lens. There are no scratches on it but it appears cloudy (see pictures).
The camera battery will need replaced.
So, the bottom line is, I think this camera works BUT I cannot prove it, so I can't list it as "working". That means you get a price cut.
