Looks like a Herter's Model Perfection from the '60s. I had one, my eldest son has it now. Mine was a 1973 model and was a single color of wood, bubinga I believe, and the glass was green both belly and back. Mine was a 56", but I had another that was a lot shorter, I think 48".
The 56" is a good shooter. The short one was a finger pinching son of a gun, so someone else owns it now.
I think they called all the recurves with this style riser Model Perfection and made them in a variety of lengths.
I paid $37 for mine in 1973 at the Herter's store in Waseca, MN...brand new!
