These pistols were manufactured between 1955 and 1962 and had a very futuristic, space age design that utilized a cast aluminum frame in lieu of the standard steel frames of the day. It 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 with an exposed hammer. It was fitted with fixed front and rear sights. The left side of the frame is marked "WHITNEY" and the right side is marked with the address markings. Includes an original Whitney box and the book "The Whitney Wolverine" by Antonio J. Taglienti.
