I think its a jumping saddle, can't really tell the difference. I jumped in it. Its obviously well loved but theres nothing more comfortable then HIGH QUALITY, broke in leather. I paid $300 for it a couple years ago and it was worth every penny. I sold the horse it belongs to and I don't need it anymore. The girth strap thingys should probably be repaired but its just annoying more then anything, I rode in it for 2 years with them like they are and never had a problem.
I also have a 44'' girth that matches the saddle. It has elastic on one end and the previous owners initials stamped by the buckels. The stamp is un seen while in use. It has some cracking but its still perfectly usable. Make a reasonable offer, I need some money for hay...(pictures will be up very shortly, I have to get on my other computer)
