Kyhunt,
Your Cadet is a Camillus made, circa 1971/1972 through 1984. I would have to know more construction details to ascertain a more exact era in that range. By the way, all Schrade made 303 and 301 models are stamped BUCK / MADE IN / U.S.A. as are all early Camillus contract 300 series models. Camillus made knives have a pivot pin in the bolster(s) while Schrade made contract knives were made without the pivot pin.
