This is an old saddle. No rivets are visible on this saddle so cannot identify that way. I believe it is an old Bona Allen saddle. Everything on it is original except the latigo which I added after buying it. The latigo keeper has 3 sets of numbers on it. the number 5, a set of numbers 1229 and then in larger numbers 3948. I know it is a 15" seat and a 6" gullet. It has old brass "D" rings and wooden stirrups. The stirrup straps are laced and not buckled.
