Hi all: I just received a Zenith Vu-Flash today in very good condition. The lens, body, shutter, and front glass pieces are in excellent condition and the camera seems to work properly. There's one thing I'd like to do though, I'd like to clean the inside of the glass on the view finders, they're dirty. Looking through the front lenses of the two view finders I can see that the mirrors, especially the one for the top view finder are extremely dirty. I'm assuming that unlike SLR cameras the mirrors on this camera are the common variety consisting of a piece of glass with a reflective coating underneath. Is it practical and safe to gently pry up the metal border around the view finders or should I remove the front of the camera from the rest of the body? How would either task be accomplished? I don't want to damage the camera in an effort to clean it up. While I'm on the subject what speed 120 film should I use say on a sunny day? I have rolls of 100 and 400 speed film. Thanks for any help you all can offer.
