This should be a Nomad model made in 1962. Not a Buckmark although similar
Made in the U.S.A.
Never made in Belguim
The Browning Buckmark is a very well made, durable, reliable handgun. I am personally partial to Rugers and Colts, but also like the Brownings.
The Buckmark is a newer version of the same design.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.
