I took this off of a 1950 straightbar Schwinn. Pretty sure it is original. I did a vinegar bath and light clearcoat on the frame. Obviously the top has the tears on the sides. I think wear tabs were there originally? Anyway, in this condition what would a ballpark value be? I've tried to find similar seats on ebay to watch the auctions, but didn't see any like this at the moment. Thanks for your help
