I have this Rolleicord Ia III I picked up for a good price and decided to work on it myself to get it into working condition. Fortunately, the shutter is working very well even the slow speeds and B and T modes. Mirror needed to be replaced which was easy enough. Aperture ring was a bit rough but a little Ronsonal and it's moving smoothly. I finally go the film counter to reset with the use of the same Ronsonal, but sometimes the counter takes a few too many turns to get from 1 to 2. After that it's spaced out pretty good. Occasionally after pushing the button in the dial won't turn. After a few more tries it does. I have a sample roll to use to test this part of the camera. One last thing. The focus knob is a little stiff and I would like to fix this. Any ideas on how to fix these two things? I'm hoping I don't have to peel back the leather to access the side panels but will if I have too. If someone knows of a place that has a repair manual or the exploded views of the side panels that would be great.
