I have a Stubben dressage Tristan Saddle for sale with a 17.5" seat, d ring to d ring 9" and a Stubben 29.
It has only been used lightly for competing in dressage and therefore has very little wear and tear.
All Flaps are in excellent condition and girth straps are good too.
It is in two tone Havanna brown on both seat and saddle flaps.
Very comfortable balanced seat, only for sale as sold horse.
I am happy to post out at cost to yourselves or you may collect.
