Sash weight identify

Question

The window is around circa 1965 and there aren't many markings on it. It does say Anderson corp. bayport minn. and a stamp on it " A 3 19 7"

Welcome to SWISCO. There may not be many markings, but there is one that matters. Our 24-331 Andersen balance will replace balances marked "3 19".
