Hello shutterclank,
I only saw the reply now. I thought there would be a notification from the system re. replies. I did get a 3 page circuit diagram from Wetzlar, but the agency in Cape Town is not really geared for R models. They sent the camera to Germany, however, Leitz was not willing to repair it. Would be un-economical. So, I have to use the camera on the manual 1/100 or any time exposure on B, as long as can guess the slow timing. I have a couple of projects for studio photography, where I can control the light and stick with a precise 1/100
Hope to publish some examples of my work still this year.
