Circle Y Western Equitation Leather Saddle size 15.5 inch seat in a Medium oil #24952559089501. You are not just getting a saddle. You are also getting a matching Headstall, Light oiled Leather tooled girth and a Quilted navy blue Big D Saddle Bag. Nice starter set or schooling set. Appears to be a Semi Quarter bars. The gullet measures 6" width with a tree length of 6.5 in height. I was measuring wrong. I do apologize for the confusion. There are some darker areas one being on the left side Stirrup leather and on the stirrups. Couple of spots on the seat. Silver with gold accent flowers are a bit dulled and some pitting seen. It will need further cleaning. No cracking seen anywhere on the saddle. Matching Headstall has a little dry and will need more conditioning. Leather Girth is slightly lighter than the saddle. Nicely tooled though. There is some marks seen that may clean up. Was used originally for a 15.2 hand Quarter Horse. This saddle is extremely comfortable. Please feel free to ask any questions.
