I just got this antique beauty from a relative. I really like the look of it very much. However, i have a few question about it. It seems to shoot in half frames, that is a 12 roll film would be able to shoot 24 exposure due to the half frames. How would the printed pics be like? And the light seal material has broken up into a mess. How would I clean it and refoam it myself? I would like to learn to do it myself. Thanks!
