Balance is stamped with 22 3 KO Caldwell.
The windows are different sizes. Does each one have a different Size balance?

Thanks for posting. Sounds like you have a 23" block & tackle balance with a stamp option of 2230. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.

I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
