914 Windshield inside OEM Glass Sticker logo?, Anyone making these OEM Windshield Mfg. Stickers Options

[TJB/914]

Looking for help if anyone makes these OEM Windshield Sticker's?
Are they different for every model year?
Many years ago while restoring my 914 I used a solvent to clean up the windshield glass & destroyed the letters. I would like one for my OEM original windshield (IMG:style_emoticons/default/pray.gif)
This is off as recent 1976 in a local shop for repairs in this photo.

given vitamin's big explanation and thinking about it.

i reckon whether its toughened (tempered) or laminated float (plate) is taken up in the trade (brand) name of the glass.

in the front screens that being KRISTALL. referring to a copyright name for a particular way of laminating the glass with particular interlayer and certain specific process and machines. made by KINONGLAS.

and in the side windows and rear windows.
DELODUR - meaning toughened or tempered and a registered copyright name for a particular process for doing it in a particular factory. made by SEKURIT.

and yes i think you are right Jeff.
the F refers to what you might call tint. or more correctly heat protection.
except i think it amounts to a naturally darker glass by composition rather than tinting as we normally think of it.
if there is no F its not heat protected. ie the 1 designation on side glass.

this naturally darker glass is used on side windows but is toughened and tempered using the particular manufacturer and copyrighted process.
and same goes for windscreens except lamination process.

that would be my guess.

beyond that you are going to need books with M codes and/or the german tables for D codes. way beyond my pay grade or i suspect standard internet searches.

if you could accumulate enough examples i am sure it does come down to the 4 different screens in the PET. its just that the description might slightly change through the years.

there appears to be basically an F/F front screen.
and then there appears to be variations on IRA/S front screens.
earlier ones appear to say IRA/S
later ones say FIRA/F but maybe not same. because there is that pesky F again.
but they seem to be later screens that have FIRA/F v earlier screens saying IRA/S.
i reckon its more or less the same thing.
it appears to be the alternative screen to more common F/F.
the other variants say either F/F or nothing.
all the ones i have found appear to have the HI tacked on the end whatever the IRA/S FIRA/F or F/F. so i don't think HI has anything to do with heat protection glass.
what HI means - i dunno. high impact? or something like that?
