Thanks slats7! That helps me narrow down a few rosters. Like you said, John Fitzgerald wore #83 as well as Golden Richards and Clark. Judging on the size of JF, it definitely wasn't his @ 255lbs. My previous guess may be right (79-80) where I did not see a #83 in the line up. This, meaning he may have made the team but was cut before season started. Golden Richards ended his career in Dallas I believe in 1978, next Cowboy photo'd in #83 was Doug Donley in 1981.
In your opinion, the jersey's features look authentic?
