It is an older model Bates Caprilli Dressage saddle, made in approx 2000 (can't find a serial number). Well used, well loved, well looked after. Comes with girth shown in the last photo.
It is 16.5 inches, med gullet, does NOT have CAIR system.
So let me know what you think a reasonable asking price would be, feel free to post an actual price or to let me know if other photos would be helpful, thanks for your time!
