Fwd: Caldwell spring replacement

Question

I'm trying to identify a spring replacement for my window. This is a new discussion.

Pics are attached. The measurements are as follows:
Length - 29 inches
Width - 1/2 inch
Stamp says 28 3 Caldwell JM
Manufactured probably in 1994.

Thanks!!

Thanks for posting. I would recommend either our S351-29 or S390-29, depending o n the size of your bottom shoe. That is the only way to confirm which balance you have.
