The markings read 26 3 caldwell. From your website I believe this is am S380-27. It is 1/2 in wide. The metal channel is 27 inches long. The bottom guide is 1 inch deep and both are winged. Do you agree?

Hi there!

Thanks for reaching out to us. If the bottom shoe is 1" deep, you'd definitely want the Series 380. You can also select the 2630 stamp option for the replacement balances.

Please let us know if you have any questions!
