Two thoughts go through my mind. Lucky you! and What a disgraceful way to treat a valuable running vehicle!

I wouldn't worry about the German marked part. Somethings are generic enough that they would have gotten into the supply system under normal circumstances. A piece of safety glass could have been shipped to Canada and cut to fit almost anything. It might even have been done at a glass shop in Vancouver. By the end of their service lives, the expected stocks of parts would have been exhausted and local purchase permitted. Rob Love will have stories on this topic, I'm sure.

If the markings are genuine, you might get lucky flogging this vehicle back to the last unit. Very few authenticated examples get to make a round trip, and you may find a very willing buyer.
