I'm guessing he needs a med/wide tree (approx 4.5 - 4.75" felt to felt) with panels that are fairly flat from seat to back, and a wide channel through the gullet. I have included a link below to pictures. The tape that is placed on his back in some of the pictures marks the approx location of the felt under the pommel of the Toulouse and the back of the saddle. I also did a spine tracing, wither tracing (approx where the felt points are under the saddle), a tracing 10" back from the first, and a tracing at the back of the saddle. As you can see in the pictures, he has white hairs at the base of his withers and along either side, which was caused by his previous owner's Childeric that was apparently custom made for him. I am a bit wary of Childerics because of this.
The saddle on his back is a 17" Toulouse Merina, medium tree that now measures approx 5" felt to felt. I have used a Fleeceworks Perfect Balance pad with front and rear shims since I began riding him with the Toulouse saddle back in August. As you can see, the Toulouse is not making very good or even contact in the back or the shoulders.
I hope I caputured enough information! I do plan to have something adjusted after a saddle is decided on to ensure a close to perfect fit.
I'd love any recommendations for saddles that might be a good fit for his style of back. I'm really hoping to go with a Frenchie (Deep Seat Butet, Devoucoux, Antares, Delgrange). I'd like something with a deep-ish seat, approx 17" (I'd prefer to be a bit snug in the seat as opposed to having too much room), semi-forward flaps, standard length (13-13.5") flap, with front and rear blocks.
