Yugo 7.62x39mm ball types?


What was the nomenclature of the Yugo made 7.62x39mm ball cartridge with “PS” type steel core? Was it M-59? As far as I know, this type was made from 1965-1967 and was replaced in 1967 with the M-67 ball cartridge with lead core projectile. Any pictures of an early Yugo box with these steel core ball cartridges in them?
