non-tilt channel balance

A handy person from colorado says:
I need to replace the channel balance in an EFCO window. The part number on the old balance is 3872L. What is the direct replacement?

I'm afraid I wasn't able to use that stamp to identify your balance. Stamps only tell us how strong the spring is, plus yours is pretty peculiar even then. Would you be able to show us a couple pictures of your hardware? I'll need to see both ends and the stamp. Thank you!
