Frequently Asked Questions
Q. How do I read my serial number?
A. In the 50 years of Circle Y, there have been many configurations of serial numbers. (Actually is the model number. The serial number is the date code of the current saddles).
In older saddles, less information is coded in the numbers. Additionally, standardization of the numbers in some years is not reliable.
To help you decipher your number, we have attempted to provide some guidance here. Please remember the saddle could be a discontinued style, and no information for tree sizing, pricing, and category of the saddle will be found.
Other names used by Circle Y that may appear on your saddle
Circle Y had several locations that made saddles for them in and around Yoakum. Here are a few names that may appear on the saddle.

'SP' in front of the model means Special for special makeup.

These numbers vary greatly. The first three would be reliable as the style number of the saddle. Beyond that, it could be different. Serial number example: 1234-4567 123= style number of saddle
4= could be seat size number on some saddles. Measure for best information. The rest are unclear.
