If it doesn't fit but you want the Brooks saddle, and you are willing to take the time to list various other parts from it on ebay (even including the frame, ultimately), you will definitely get your money back. Every single bike component in reasonable condition I've ever listed on ebay has gotten multiple bids, and some even sold for close to the new price! pedals, cogsets, cranksets, whatever, you can do quite well on ebay if you're willing to spend the time taking photos and writing up ads. Good luck!
