Is the cab rear corner curved glass toughened?

my truck and I were in the same place today and I checked my windows. Near the bottom is etched:

"Herculite"

"AS 9-88"

Try as hard as I might I was unable to get it to show up in a picture.

that's what is etched in the corner of both of my corner windows, too.

Here is a picture of the corner window markings on my US built 1953 B4B 5 window.

Just took a bit of back masking to bring out the markings in a picture.

Cool, thanks for that. All the other glass in my truck is marked "Armourfloat Safety Glass" but the corner windows are definitely not marked at all.

Actually, my drivers window is marked "Armourfloat Safety Glass - Antisun" and has a slight green tint to it, which is interesting.
