saddle for sale brand new only used once

I have this saddle that I had bought for my 7 year old brother and he only used it once and I just want it to go to some good use im asking 150 email me if you are interested it is a 13in saddle

What type of horse did he use it for/did it fit?
My son has loves to ride our horse, but we don't really have proper tack for him as he had zero interest in riding when we started getting things together.

He used it on a quarter horse and I put it on my thoroughbred the other day just to see if it fit her and it did
