This is a Herters Spring Length 52.5 Recurve Bow from Waseca, Minnesota. M580573005 is the writing on the wood grain.
I have no idea what that means. It has a 28" draw, it is 50lbs weight, with a 58" strength length, and is 52.5 from tip to tip.
I notice one surface scratch that doesn't appear to go through. It appears to be in really good shape for a bow that is probably from that 1960's-early 1970's. The wood grain appears to be in great condition as the bow appears to have been not used much.
