Hi Aidas,
I think there are some interesting differences between the two 1951 2/50 ZK lenses: yours and David's...
Anyway, a genuine 1951 ZK would be a novelty (for me!). But no doubt KMZ could have found some old parts in their boards! It would not be the first time...
I have just checked my datas: all these lenses (the 1950 and 1951 ones) have 7 ciphers, not 6 ?...
Amitiés. Jacques.
