In the late 70's early 80's up through the Mainous years Burton had what I would call a Zorro for the Raider logo. Pictures of the 1972 team it was plain white I think there was a orange stripedown the middle.
Miller came in for his run and had the black B, then Shupe went to a orange one, which we had to take off our helmet after games and stick in our locker until gameday. He was tight with money and figured we would use up less by not getting them beat on in practice.
