17" seat in true Prestige fashion can accommodate rider who takes 17.5" seat. Tree is set at original 32, but can be adjusted up or down by saddler. Measures 3.5" from dot to dot, so I'd say it's on the narrow side of Medium. 13" flaps. Leather is buttery soft and sticks you in it beautifully. Usual age wear, very well cared for; had professional stitching done on underside of padded flap. Saddle is for sale locally, listing will end early if it sells locally.$50 flat shipping to Lower 48 States, all other locations ask.
