I knew Ralph from back in my Arrows by Kelly days. He built a really good bow back then, loved shooting and hunting with wood arrows, too. Think he maybe even advertised his bows in Traditional Bowhunting magazine back then.
How many pounds is it? It is in pretty rough shape and appears to have snakeskin on it. Hard to tell because your pictures are so large. I assume you don’t have a string?
What are you wanting to do with the bow, keep it to shoot or display, sell it, etc?
