The Buckmark is a newer version of the same design. Challengers came in 3 models or versions (I, II, III), each being made after the former was discontinued. The Challenger III was very very close to the current Buckmark design, with the aluminum frame in common with the Buckmark. Challenger I and II both had steel frames.
IIRC it was contracted out.
