Here are some more informations, I found regarding the Sovjet color tv sets. Color television was introduced in the Sovjet Union on Oct. 1st, 1967, on the same day, when France started with color television.
Two factories produced color tv sets: the Leningrad Kozitsky Works produced the color tv sets of the brand "Raduga", starting with Raduga 4 and Raduga 5 in 1967. The Raduga 4 had the 70° picture tube 40LK2Z, the Raduga 5 had the 90° picture tube 59LK3Z, see

The Moscow Radio-TV Works (MRTZ) produced the color tv sets of the brand "Rubin", starting with Rubin 401 in 1967, see
