I am almost 100% positive that is a paragon saddle. And as Freia said, those are cheap junk. At least in my opinion.
If it does happen to be a paragon saddle, I would highly advise you to spend your hundred dollars on something else more worth it. Also, if I may say so, the saddle is quite ugly, and looks cheap (in my honest opinion)
That lady may have PUT the saddle on a Arab, and a Draft, but it surely does not mean the saddle FIT the Arab and Draft both. Nu uh.
I would say pass on this saddle...
