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.

I think this thread is hilarious. I like to read the BAT auctions for 356's. Those guys are anal but entertaining. You guys are having fun with glass and interesting and entertaining. One can always learn something new about Porsches from threads like this.

Absolutely fun. That is exactly why we are all here on this forum with our lovely (IMG:style_emoticons/default/wub.gif) little 914s on the driveway (or on jack stands) !!!

Poo poo to the naysayers...

I looked at my 914s last night... Some interesting observations.

The 74 that has the Sigla w/s has DOT 25 (DELODUR) tempered glass all around. I think it is safe to say all 914s have this supplier (DOT 25) for all tempered parts. Then there are variations DELODUR -1 / - F / -1F. Not sure if we will ever figure that out.
What we should be doing is looking at the M number. That is recorded somewhere. Either at the manufacturer (for sure), but I would think they had to be submitted to the DOT, or the NHTSA for safety compliance. Question is, who could be asked to dig up 50+ year old records...? I'm sure they must still exist in a filing cabinet somewhere...

The 74 has M173 (-F) on the sides. This is the tinted glass EXCEPT for the left side large door glass, it has M202 (-1F). To me that means it has been replaced somewhere in time. M202 would be a different piece of glass - likely either the tint composition / raw glass supplier or the thickness. The back window is M93 (clear glass).

On the 73, the tempered glass is M93 all around meaning it is all clear glass.

So the takeaway for me is you could order heat protection glass for the windshield, side glass (M173 or M202 for tint and M93 for clear) or a combination, but the back glass was always clear M93 (M930 with a heating grid).

you are dead right @vitamin914 .
DOT 25 - all that comes from flachglas gmbh.
they do all the toughened (tempered for Jeff) glass.
branded as delodur.

and also the sigla windscreen you have. DOT 25.
you have a full flachglas car mate. pure breed. it would be all original glass that one.

i've got the factory cross bred mongrel. (IMG:style_emoticons/default/biggrin.gif)
with the DOT 31 windscreen. kinonglas.
swallowed up and disappeared a long time ago into the Saint Gobain empire of world domination. that company must have no cheese eating surrender monkeys on the payroll.

EDIT
ps your one piece of 1F sideglass is the glass they started using in 76 for tinted instead of F. supercedes the F i think. so its had a broken window down the line and the replacement glass has probably come from porsche as the new part.

yes on the "tinted" windscreens too being properly described as heat protected.
the SIGLA looks like it did it with both laminations being a green glass. SGG
the KINONGLAS did it with only the outer lamination being IRA (infra red absorbing) glass. FIRA/F.
clear versions of the windscreen are notated with an S for Sigla and with F/F for Kinonglass. i have to get my F/F out in the sunlight to see the colour. think its a kind of bluish grey rather than ultra clear - so even the "clear" or standard kinonglass one is kind of darkened. but hey i am probably color blind.
