Bought exactly the same camera (with the Zeiss-Ikon-Voigtlander badge) a pair of years ago with great enthusiasm and high expectations, however it turned out that the shutter curtain had pinholes. I brought it to my technician in order to have the curtains (which I had to import from Japan) replaced and it's there since at least one year: he first ruined some parts when disassembling, then made several mistakes with the meter and asked me to purchase the tech manual from Germany, mounted the self-timer top-down, then the shutter times and the meter went off-calibration, etc etc etc. Still there. I wish better luck to your unit!
