Buffalo Bills Helmet - 1965-73 Throwback Helmets by Riddell. Riddell is proud to make this full size “TK” suspension helmet with 2-bar facemasks as worn on-field during the ‘60s, ‘70s, and ‘80s. This Buffalo Bills Helmet offers it all. The TK consisted of a web suspension system in a rounded shell, with the Riddell 2-bar facemask worn by so many great Buffalo Bill players of the past. This helmet would be like the one OJ Simpson wore back in his playing days. This is a very good looking Buffalo Bills helmet with the red buffalo on both sides of the helmet.
