sash balance

Question

I removed  2 sash balances from and old Andersen window built in the mid 1970's.  I can't make out the windo model type etched on the glass, but I have the old part.  On the part are the numbers B224p19/576.

Hello!

Take a look at the 24-431 Andersen sash balance which is designed to replace balances that include the stamp code 419, or 4p19.
