I just purchased a Root Kadet longbow, same glass color, and same riser with leather wrap and paid $56. I was told that the info being stamped in the riser indicated pre 1960. A friend of mine has a recurve like yours, but with draw weight and info printed on with black ink, which he purchase new from Root in 1962. This bow was a factory second, with slight blemish in the glass, and cost $24 direct from the factory. They were made here in Big Rapids Michigan before Shakespere bought them out.
