Manufactured between 1955 and 1962 with a futuristic, space age design that utilized a cast aluminum frame in lieu of the standard steel frames of the day. The Wolverine was a straight blow-back design that used a round bolt inside the upper part of the frame with exposed cocking knobs on the rear of the frame and an exposed hammer. It was designed by Robert "Bob" Hillberg (1917-2012), an intuitive firearms designer who worked for High Standard Mfg. Co. as the head of research and development, and was involved in a number of different design projects including the COP .357 Derringer pistol and M37 machine gun. Features fixed front and rear sights, standard markings, and checkered Bakelite grips. Includes an original Whitney box signed on the front in sharpie "To my friend Charley Petty/Bob Hillberg" along with spare trigger parts. Charles E. Petty Jr. (1939-2022) was a contributing writer for several well-known firearms publications, and authored an article on the Whitney Wolverine which was featured in they March-April 1982 issue of "American Handgunner" magazine.
