The manufacture of your windows is Herr International in Chesaning Michigan 517-845-3061 and is still in business. I purchased some rubber glazing for my windows and it turned out good. They only had black, but it looks good. The P/N is 009-311 and isn't a exact match. It didn't contact my window enough to create a good seal between the rubber and the glass. I had to put a bead of silicon calk inside the rubber glazing to seal it. The outcome was a good looking glaze that seals. When installing, soaking it in soapy water makes it much easier to fit into the window frame. Good Luck.

Would anyone be aware of a source for window molding (crank out windows, kind of resembles the letter L with a lip to catch the frame then kind of rolls over the window about a quarter of an inch.
