Nice find. The question of refinishing or not isn't that hard to determine. You know what you paid for the bow, but ask around and see what fellows with similar interests would pay. If there isn't interest enough to make it valuable; pick a number, say $300 or so, then it probably isn't going to hurt the value much to refinish it. I have yet to regret refinishing one of mine.
The problem comes after you have it all prettied up and no longer wish to shoot it for fear of putting new scars on your new finish.
