type your model in ebay and then look in the left margin for the sold items and it will show all the ended auctions and the prices. I think green means it sold and red means it didn't sell.
I think all those older vintage bows sell in the 200-300 range. You don't get much for the accessories sold on the bow. if you have the time and want to maximize your price you can take the sight and anything else of value off and sell those separately.
