This saddle is an awesome saddle that never gets full use (husband's saddle). No marks, like new. Medium tree, 18" seat, 16" flap. It has a patented plybond spring tree and the finest of European leathers. It's VERY comfortable and light, has been oiled, and looks gorgeous. Not slippery. Stirrup leathers are included. Wool flocked. Amazing saddle, amazing deal..Asking $1600. (I put American Flex but it's not. I just chose that arbitrarily as there is no Exselle option. It is manufactured by Walsall)
