Purchased NEW in 2013 but manufactured several years earlier... it was from a closing tack shop and new as in never been on a horse! This model currently sells for @ $3500. It was NEW... as in never been on a horse... when I bought it last year from a closing saddle shop but was apparently manufactured several years ago. Used maybe a dozen times and in like new "Demo" condition it is Kieffer size "1" (17-17.5) ...Kieffer makes 3 seat sizes on this model (0-1-2) and this is their AVERAGE. It was originally a Medium tree but was fitted to my Wide horse... the tree is readily adjustable by Kieffer or any qualified saddle-fitter. Visit the Kieffer website for model specs and info. Purchased for my (5'9/160#) rider who is now in med-school with NO time to ride... it is too big for me (5'2/105...I need a "0" seat) SO MAKE AN OFFER... MUST SELL!
