Nice older model, but sound in every way this is a Tony Slatter dressage saddle, made in England. Cannot find too much information about Tony Slatter but this saddle looks very serviceable. Would assume by the stamp 6103 98 that it could be a 1998 model. The seat size is 18ins and the saddle flaps measure 17ins from the stirrup bar to the bottom of the saddle. We measured the tree width to be in the region of 5ins, which we regard to be a medium width fitting. Spring tree.
