Help On Cowboys Durene Jersey

[Peterson28]

I am considering buying a older Cowboys durene jersey of OL Pat Donovan. His rookie season was 1975, but I am not sure if this style jersey was from earlier dates or not. If anyone can help me on if they wore this style in 1975 or later I would appreciate it

This style was used in the late 70s. I've never seen a durene version like this but have seen the heavy stretchy knit ( a cold weather material I was told) and a mesh.
