With FSU cameras, it has always seemed to me that the older they are, the better they were made. I am a Contax fan, so I have a few Kievs. Here is my oldest one, from 1949, with a scarce collapsible Zorki (later Jupiter-8) lens. These were only made for a very short time, and I also have a fixed mount ZK lens with a serial number about 350 higher. I think the production of the two versions of the lens overlapped in 1949. I recently got the collapsible lens, and all looks great, but I have not tried it with film yet.
The camera works just fine, and did not require any cosmetic restoration other than cleaning. The chrome on the early Kievs is a matte finish, and seems to be much better than that of the prewar Contaxes. It came with a very well made leather case, at least as good as the Contax ones.
I would love to get one of the early Kiev prototypes from 1947 or 1948, but they are very scarce, and have too many digits in their price tags!
Cheers,
Dez
