Well, here is the Zorki 4K immediately after its rangefinder test.

So far the 4K has passed inspection and I will know tomorrow after processing the first two rolls of film whether the transport, shutter, and rangefinder are good. Mine was made in 1975 and came with a 1984 Jupiter-8. Lens and camera are in quite excellent condition (thank you Fedka). Unfortunately, the Kiev 4AM that accompanied the Zorki was not in as good a shape and will be headed home for an exchange.
