This a great helmet from a great era at Texas. The Riddell "RAC-K2" is a "RK-2" model with factory installed "AC" or "Aero Cell" padding. The helmet bears a 1963 date stamp which means that is probably was used during the glorious Tommy Nobis era. The helmet is missing the player numerals which throughout the 1960s were located above the "steer" logos, yet there is still visible discoloration and glue residue in where they once were. The double "Riddell" stamping on the rear of the helmet indicates that the helmet was sent back to the Riddell factory for reconditioning at least one time. Texas also used Marietta helmets and face masks in the 1960s and the small extra hole above the Riddell "BD-9" face mask suggests that it may have been fitted with a wide mount Marietta mask prior to the mask shown. This spirit and pageantry of 1960s era college football is legendary and this helmet is a great symbol of that unforgettable period.
