etched "A" on drivers door window (Daytona)

Chassis number please.
Plus photo of the etched "A" (I do know how it looks like).
Plus photo of the ID tag in the engine compartment.
PLEASE.
Thank you.
(yes, have seen quite a number of Daytonas with the etched "A", none of the restorers around Modena has an answer nor does Classiche, have already asked at least five different sources in and around Modena and Maranello).

looks more like a D and A together

 

i just saw the same A on the rear window of an original usa DINO.

Makes me wonder if this ^^ means I might be the only person to likely figure it out.
Hopefully not, but wouldn’t be a first and proves OCD can offer some advantages.

I recognize that car.
Years and miles of great memories with her.

 

im on the edge of my seat. giddy even.

 

Now put that energy and excitement into research instead and you can become a hero.

 

a hero like you

 

A secret code sign for cars owned by the IlluminAAAti?

 

Well, never been my aim, but unless you do it yourself, ...
... you may have to wait awhile.
I may include a paragraph or two in a book I hope to publish someday about countless other obscure and strange details I've encountered and researched while working on old cars.

 

16501 has them as well

 

This might even sound offensive to ask but could it be something as simple as the glass manufacturer's mark?

 

not all daytonas had it and now its been seen on a dino. the maker is identified as securit. this could be a subtype of some type but nobody really knows.

 

I was able to look at #16763 today and both rear quarter light glasses have the etched "A" like my previous, and Marcel's photo.

I am 99% certain that this is the marking put on replacement glass that was manufactured for Marpart, now Maranello Classic Parts here in the UK. I don't know who made them, but I think it was just Dino and Daytona glass.

I remember seeing the "A" in new cars of the 70's, not aftermarket

See post 4 in https://www.ferrarichat.com/forum/threads/dino-246-rear-window-screen-glass.649520/#post-148152694 for “A” on late 1973 Dino 246 glass.

All DOT approved safety glass since 1 January, 1968 in the USA had AS1 for the front windshields, and AS2 for side windows, denotating the type of safety glass being used in different locations/ applications.

According to St Gobain website it is confirming the glass complies with a hardness test. Only applies to toughened glass not laminated

We talked about this many years ago on here, the curved A is on some cars from Europe and the UK as well, but a low proportion, there was no real answer.

 

An additional datapoint from Dino 06236, built April 1973 for the Italian market, original glass. The vent window has a curved A and the main window has a simple capital A. Image Unavailable, Please Login
