If you're able to ride an endurance-style saddle (no horn), I have an Am-Tech (American Saddlery) that might fit.
There's nothing wrong with it, I have seven saddles covered, up in the attic, that will never get used again.
I only want $150 PLUS shipping but again, it does not have a horn.
It was originally for my Tennessee Walker that foundered last year. I had bought the saddle for another TWH, then ended up buying this horse a year later.
I think it has a 16" seat, I'd have to re-measure. It's been kept covered in the attic since I bought it. I never leave saddles in the barn or horse trailer.
The beauty of this saddle is that it weighs a whole 11 pounds
With this saddle it would be sold with no return, however
I'm in no hurry to sell anything in that attic but it really is stupid to have all those saddles and not use them.
If you think this might be something that would work for you, PM me.
I am second owner on an Orthoflex from the original company when R. L. Watson was making their trees but I need to get $1,500 out of that one. It would most likely also fit the horse in the avatar. For that kind of money, I would give the Buyer a two-week trial as long as they paid thru PayPal.
