America, circa 1955 - 1962. it was a lightweight(only 0.59 Kilos) experimental sporting gun. this is what Wikipedia has to say:
"The Wolverine was engineered by Robert Hillberg, who learned about aluminum casting during WWII while working with aircraft guns and later became research engineer for High Standard Manufacturing Company. Only 13,371 of these .22 semi automatic pistols were made in its short period of production between 1956 and 1958. There were approximately 500 nickel plated according to company records, the rest finished with in varying shades of anodized blue, The plastic grips came in either a black,dark brown or white, the white grips are found mostly on the nickel plated models. The frame being investment cast by Alcoa was a new idea for the gun industry at the time, now it,s widely used by almost every major gun manufacturer today. Its name "Wolverine" was named after Mr. Hillberg's favorite football team, the University of Michigan Wolverines. A victim of extremely poor marketing in the beginning, financial problems and then being under priced by $2.00 by both Ruger and Colt with their new semi-automatics .22, the company was doomed. The Whitney Wolverine was beautifully engineered pistol, with production innovations way ahead of its time and with its very unique space-age design."
