Sticky Leaf Shutter (Voigtlander Vito B)
Have been gifted a Voigtlander Vito B which had a frozen shutter.
It's no trouble to get access to the rear of the shutter on these, so put a couple of drops of naphtha on there which freed it up immediately.
Despite re-applying naphtha 5-6 times and cleaning with a q-tip, the shutter doesn't always close after firing. It works a majority of the time across all speeds (even the timing on the slow speeds seems ok), but every now and again is lazy on closing the shutter.
Suggestions ? More naphtha and working the shutter ? or is it disassembly time to get access to the front of the shutter ?
