The Perkeo I just bought had some shutter speed issues, so I sent it to Wolf Umbach (retired Voigtlander employee who still dabbles in CLA and repair of these cameras). I was so excited to get it back, but yesterday got a call from him letting me know that there's a spring missing from the frame counter mechanism, which he can't replace or fix, and he's been unable to get the lens apart (he thinks someone has glued it sealed) to service the shutter. This stinks. Does anyone think there's someone out there that can handle a more difficult repair like this? I know about Jurgen, but I'd rather not go to him. I was hoping there was someone who specialized in Voigtlanders and might have many spare parts/experience with these. Many thanks.
