Well, I answered my own question (no thanks to you all!
Just kidding!
). It was made by PPG. Someone on another forum mentioned all the glass was Libbey-Owens-Ford, but I thought the hatch was PPG, and mine was. Those glass articles I posted also implied all the rest of the glass was LOF EZ-Kool. Anyway, it got me worried mine was replacement, but my worry was for nothing.
