Well done Tom.

Is this the lens that the Helios-44 copied? It has been said that the Russian version in time improved the breed but a CZJ version must have also been a later Biotar version from the Carl Zeiss firm.

Thank you Tom

The second version the silver Biotar from early 50' they copied and later as you said gradually improved, but Biotar genetics are obvious. Her are the photos from Helios made in 1984:
