Going by "verjag's" location line, maybe he should seek advice closer to home!
I have both Zorkis and three Kievs. As for that not changing the shutter speed until the shutter is cocked, I've seen reasoned arguments both ways, and one guy who said he had repaired Contaxes and Kievs for 20 yrs. said he knew of no reason you have to cock the shutter first. Where does that leave Zorkis?? Now, if they said not to put your finger through the focal-plane shutter, I would see why. There seems to be a belief that cocking the shutter first was true on all cameras, regardless of brand, on which the speed dial rotates during exposure. So who's to say - do it and be one the safe side.
I might also mention that 3 different cameras I bought from FSU sellers
