In the picture with my gnarly fingers, the line you see logitudinal in the middle of the glass is the sandwich layer of plastic sandwiched between the two layers of glass. This is laminated "safety glass". This is in my CCPU which was fully restored in the early '80s.
Picture of the door glass in my unrestored Town Sedan shows what I believe to be original plate glass. The chip is definitely not tempered glass, and there is no evidence of any of the side glass having been replaced over the years. No evidence of lamination either. The chip looks like what a chip in any other non-tempered glass (say, the mirror on the back of your bedroom door) looks like. (All the side glass will get replaced when I tear the car down for restoration this summer.)
The replacement glass that the vendors sell states that windshield is laminated "safety glass" per Federal law. Side glass specs seem to vary, some sell 3/16" "tempered" while some sell the same spec as windshield, namely 1/4" "safety glass".

Thanks, Jay Jay, for your nondestructive tips. I’ll check my car when I get a chance.
