I have been trying to identify my dressage saddle. It is marked Collegiate RD 65045, it is stamped 17 and it also has a stamped number 800227135 which I think is the model number. It has large knee rolls with long leg flaps which measure 18 1/2 in from stirrup bar straight down. It was bought for me in late 90's and I would like some information on it. What model it is, what the worth is. Thanks in advance for any and all information you can give me.
