It might fit your new horse hang on to it, or if new one needs another saddle p/x with saddler. Second hand saddles seem to go for peanuts I would hang on to it.
I have never heard of the make - so if I were looking for a secondhand saddle I would not be prepared to spend much money on it (or possibly even consider it) I'm afraid, that doesn't mean it's not a good saddle but it does mean you might have a limited market and would have to price it accordingly.
I presume you bought it off a saddler that specialises in this make - if so I would try and get them to sell it on your behalf or take it in p/x against another
Guess I'll hold on to it for a while. They are brilliant saddles esp. for TB's with high withers. You hardly ever see them 2ndhand presumably because people like to keep hold of them.
