I picked up a Voigtlander Bessa 6x9 folder, with a Compur-Rapid shutter, and a 10.5cm 3.5 lens.

Cosmetically the camera is in pretty good shape. The two big problems are the shutter, and that the lens does not seem to want to sit square, to the film plane. It seems to want to tilt upwards a bit.

The shutter appears to be in major need of a CLA. The question is, does anyone have a decent reference to do this kind of work? I've never taken one of these bad boys apart. Even though I got it for cheap money, I do not want to ruin it. I've worked with plenty of electro mechanical devices that were plenty sensitive, and chock full of small parts, over the years. But I also know that a good reference manual, or other source, can help save some really bad mistakes.
