I think it is an all purpose, or like said a trail saddle.
The saddle will sit differently on a horse than in the pic, the pomel will sit higher and the flaps will sit further forward, I think. Also the stirrups will sit to far forward to be an effective dressage saddle. IMHO.
I don't think its a dressage saddle. It's not deep at all (which the majority of dressage saddles are) and most won't have those rings at the back.
I would guess trail or endurance.
Scratch that, its definitely endurance.[/edit]
