[Chrysler300] Glass Standards and labeling

["Rich Barber" <c300@xxxxxxx>]

In discussion responding to my questions on PPG glass markings on my 1955
C-300, I received the hot skinny, or at least a reasonable explanation of
numeric codes on the various pieces.

Wayne Graefen suggests the following and it makes sense on my car.
Interestingly enough, the front glass may have been manufactured in March,
1955?the same month as the car was manufactured.  Just-in-time parts
delivery in 1955?

Thanks to Wayne for this information (copied below, with permission).  Now
I've got to find a PPG SOLEX DUOLITE passenger side glass date coded 35 or
earlier.

Glass Standards and labeling

I would read what you have given me here as made at plant #9:
64  June of '54
15  January of '55
25  February of '55
35  March of '55
 
but then I'm applying '57 300C info to your car.  These manufacturers could
change how they did this.

AS-1, AS-2, etc. are indeed glass standards.  
"American Standards - First Quality", etc. is the interpretation in the
glass catalogs.
You will note on shaded windshields that the standard marking has a line
above it.  This is to indicate that up in the shaded area it does not meet
that standard for clarity.
Side glass did not need to be as perfect so was slightly inexpensively
produced as AS-2.
First number following may be the production plant where the glass was made.
The last two numbers standards are date code for month and year.
In 1957 I find that virtually all original glass carries date codes within
six months of the production date of the car itself.
