Geez- they look like the finger holes on a bowling ball. I'd be extremely cautious trying to clean the mirror, its a 'first surface' mirror, you could easily remove the coating. Thats something I wouldn't try, but then I'm a total clutz these days.
Check one of the earlier threads on the new Silver Shade film before you go trying to clean the camera. Odd spots, stains and other "defects" seem to be quite common with this first batch of the new film.
