I have an older home with MANY double hung windows. When a window is broken it ruins the old pully system as a 1929 "enery saving" system has to be removed which is impossible without ruining it.
In the last few years I have replaced the pulley system with a modern tention window channel system that works much better than the lead weight system but my local store no longer has them. Any help on a supplier?

At this point I want to keep the original window sashes, just replace the pulleys and window seal system.
