It is definitely a Crosby saddle, there are buttons on each side of the pommel. The cantle is low, not flat, but certainly not raised, like say a dressage saddle is. There aren't any knee rolls, so it definitely is close contact. It looks very similar to the cc saddle pictured below, except higher quality leather.
Oh, and the seat size is a 17. I'd probably be more suited for a 17.5, but if I can get it for cheap, I think I can deal with it being a 1/2 inch too small.
