I'm selling my 15.5" medium tree dressage saddle as I recently outgrew it. It has a nice wide gullet channel, long billets, and ample wither clearance. Synthetic leather makes it easy to clean (wipe it off with a wet sponge). Always stored inside and covered, well taken care of, immaculate condition. It fits my Thoroughbreds, who both take medium trees. Price reduced to $300 plus shipping.
