I'm looking at buying a secondhand Stubben Tristan dressage saddle (cause we all need more saddles, right??). It's a 31cm gullet or tree or whatever. I see on the Stubben website that past that the saddles really only run to 32cm, or X-tra Wide.
My mare is a wide, flat withered Arab/Draft mix. I wish I could tell you what size saddle I currently have but I really have no idea. It's a western saddle and I believe the gullet is around 6.75 to 7" (rough measurement)
How could I measure her to estimate whether the saddle might fit or not? The crappy thing is I'd be buying the saddle sight-unseeen as it's located about 6 hours away.
