Canterbury Equation Custom Dressage Saddle. It is 17" seat and Medium tree. This saddle has an upgraded English leather, which is very soft and is super comfortable and was made in England. The saddle is in excellent condition. It has no rips, no scratches, and only been used lightly for a few years. Its been sitting in my tack room ever since. I used this saddle on my TB who I have basically retired and don't ride him much anymore. It's hard to part with this saddle but it's not being used anymore. I paid $4500 brand new. My loss is your gain. This saddle was hand crafted by a Master Saddler George Gullikson of Canterbury. This saddle has an adjustable tree. EXCELLENT Condition!!! Features soft and open yet supportive seat with moderate twist, extanded stirrup bars, external knee blocks.
