The old Voigtlander Vito and Vitomatics with their Color-Skopar lenses are great cameras. I had a Vitomatic which had a dim rangefinder patch but it was repaired as part of a service. I think it was as simple as cementing an optical component back in place. Personally I always factor into the purchase price a service with these old cameras. The leaf shutter in particular sooner or later will need a service. If the light meter is not working then I don't think it can be repaired and, personally, I would look for another camera. The service completed and the light meter OK, I have peace of mind. In my case I eventually sold the Vitomatic for two reasons: firstly, the viewfinder tended to flare in backlit conditions and, secondly, the camera was a little heavy. I bought an early Vito B, the one where the aperture and shutter speed adjustments are completely independent. These early cameras do not have a rangefinder so I purchased a separate Voigtlander rangefinder that clips into the cold shoe on top. This simplifies the optics making the viewfinder and the rangefinder extremely bright (much brighter than in the case of the Vitomatic) at the expense of slower operation (the focussing distance has to be manually transferred from the rangefinder to the lens). I'm very happy with my Vito B and use it regularly. The Color-Skopar lenses in the Vito B and Vitomatics are the same and all produce great images.
