The dealer at the camera fair seemed to think that this Super Ricohflex was specially made for 35mm film. Actually the 35mm option is achieved by an accessory called the Color Back, which replaces the normal 120 insert. The winding knob is replaced with a knob with a film counter. To advance to the next frame, you pull out the knob and turn it until it stops. The focussing on these is notorious for jamming with seized grease. Mine was just about usable when I had it, until the viewing lens decided to seize completely for some reason. So I had to take off the lenses and re lubricate. That was when the trouble started. The grub screws which secure the outer focussing geared rings to the actual lenses, are very tiny and soft and in no time I had ruined the heads, so I had to drill them out. I still couldn’t budge the viewing lens so I had to drill two holes opposite each other and use a spanner wrench in the holes. Eventually I got it off but I still had to soak the viewing lens in warm lighter fluid overnight before the focussing helix eventually came free. Well I managed to get it all back together and refocus the lenses. I had to worry a thread into one of the drilled out holes and got a screw into it to secure the outer ring. Its not pretty but it works.
