Looking to replace these

The only markings I saw are in the photos. it says "21 4 GL Caldwell"

I have an idea which one I need to get, but I narrowed it down to two, and I still am not sure the difference between them. Hoping someone can steer me in the right direction.
If you need anything else just let me know.

Thank you,
Ryan

Hey Ryan. This looks like either an S380-22 or S385-22. The only difference between these two balances is the depth of the bottom shoe. See the diagram below for reference. Compare both with your old hardware to see what matches best. In either case for a new stamp option go with 2140.

Mine looks like a less of a slant than the S380 so I believe it's the S385.

Thank you, I appreciate the fast response and all the help.

Have a great day.

Hey Ryan. So long as the depth is more than 1", you can assume it's a Series 385. Sometimes these shoes just wear down from age. But the only shoe like this that is greater is the one that comes with the Series 385. Let us know if you have further questions, and thanks again for reaching out.
