Unfortunatly no idea of history or value on that bow, but a suggestion. Get a new string for it, some arrows and give it a try. You would be surprised how addictive shooting a recurve can be. Especially if you use feathers and shoot of the shelf. Lower range than a compound but lighter to carry.
No sights, no rests, it's kind of throwing a baseball or football to hit your target. More of an art form rather than any science.
Try it, you just may like it.
