Model Year 1965: An early build for the upcoming model year (this photo was taken in the Summer of 1964), this early model Scorpion featured a revolutionary patented rubber track and an all-fiberglass body. Unlike many metal-based machines of it's era, this nimble little number was unusually quiet and stylish. This model was a major breakthrough for Trail-A-Sled, Inc. and positioned the firm as a true leader in the industry. Although shown here in black, the bulk of this year's build featured either turquoise of pale orange. Coincidental, this photo features the Crosby-Ironton Arena in the background, site of the firm's tragic fire in 1967. See related transcript. Mechanix Illustrated, February 1965. See Terms of use.
