Actually, Don, Darryl Starbird built the 1:1 in 1964 and Monogram created the Big Deuce kit later from the full-sized rod. The Little Deuce came along even later as an effort to capture more of the modeling market from kids who couldn't afford the 1/8 scale Big Deuce. Both kits were quite popular.
I believe it was the Big T that was designed by Starbird for the Monogram 1/8 scale kit before they commissioned him to build the corresponding 1:1 rod for promotional purposes.
Thanks for backing me up Danno. i thought that was the sequence of events on the Big T and Deuce
