The tree measures 6 inches point to point inside where the nailheads are. The channel has a generous 2.5 inches of clearance. The flap measures 17 inches long, measuring from the stirrup bar down to the bottom of the flap.
By my best judgment, I think this is wool flocked. It feels like wool and there are little areas where the stitching makes me think the panels have wool. The flocking feels soft and evenly distributed. Not compressed or broken down.
The overall condition of the saddle is like new. You can see on the photo of the flap, there isn't even wear from the stirrups rubbing. This saddle honestly may have never been ridden in. Or at most, a couple of times. There are a few light marks on the seat, I think perhaps from being bumped in storage. This saddle needs a good conditioning, I think it's very likely the dings would oil/condition right out.
I would put this saddle in a category where I would expect it to be $800/900 new. I am selling this saddle for $300 plus shipping. I'm not negotiable. That's what I am asking and I have a feeling I'll get a couple hundred more at the tack swap coming up-- but if I can sell here and save myself the hassle-- I will. Shipping should be $25-50 depending on whether you're on the east coast like me or not (I am in NJ). I take PayPal. My PayPal is firstname.lastname@example.org.
Not interested in trades. Just want $300 and a saddle shaped hole in my basement
