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 and an exposed hammer. With fixed front and rear sights, standard markings, and yellow/gold anodized trigger. Includes a reproduction Whitney Wolverine box, manual, and warranty card.
