Bill, you outlined it pretty well but there are some subtler nuances. Yes, the common Kievs and initial FED/Zorki models were faithful copies of their German prototypes.
Dear Eugene,
Another point is that most (not all) Russian changes in detail and design were genuine improvements -- I'd rather have a Zorkii 4K, made right, than an original Zorkii -- and would have made for better cameras had they been built right. Likewise there were some good, original designs (and some bad ones -- the Leningrad with its uneven film spacing and crystallising, fracture-prone chassis). Unfortunately, the general standard of execution, i.e. quality control, generally fell faster than the improvements and innovations in design were able to raise the standard.
Cheers,
R.
