I have a DG Stackhouse monoflap dressage saddle. It's a 16" medium tree. Karen O'Connor had it custom made for her and Theodore O'Connor, but there was a mistake made with the seat size. I bought it about 7 years ago. It's in amazing condition. I no longer ride unfortunately, so I would love to find someone who will take care of it and enjoy it as much as I did! I am open to offers, but please no low-balls! I spent a fortune on this saddle when I bought it. Give me a call!
