I'm looking for a real factory sold service manual for Rolleicord V, Va, Vb cameras. In particular I need a service manual for the lens and shutter assembly as I have one with a slow timer. The blades all work great at the faster speeds and B, but I can hear the timer having problems. I also have a donor camera that I can use for exploration before I start on the good one. I know I can find manuals on ebay, but most of those are less than legal reprints or poor quality scans. I'm looking for somewhere that I can buy a real factory issued manual. If you know a good place to get one, let me know. Thanks.
