This saddle is a stubben made St. Martin CTD all purpose with an 18 inch seat and a medium or regular tree. The tree is great for horses that have high withers and more of a curve to their back (basically your typical TB, WB, or appendix). The leather is in great condition, I clean it after every ride and keep it covered when not in use. This saddle really feels like it hugs you with a deep seat and front and rear leg rolls. Saddle looks almost new. Asking $500 or I may trade for a saddle with straighter panels, especially a collegiate, partial trade for a wintec, or trade for a western saddle of similar quality.
