Vintage Speedmaster crystal: A1.2 Variant?

I noticed that for the Hesalite crystals for Speedmaster from the 60s
there would apparently be a further central "Omega" markings, in addition to
the 4 described by MWO.


In fact on the references, 2998, 105.003, 105.012, 145.012, 145.022-68 (transitional) and on the very first
145.022-69 it is postulated that there should be a "A1" glass, the so-called "flat feet" narrow.


(Thank you Ash for the picture)

Apparently, however, between the A1 and A2 "short feet" type an additional one could be possibly positioned.
It looks like a cross between the two with a wider Omega, but with flat feet.



I apologize for the quality of the images, but the details are, not only difficult to spot, but even more so
to photograph.

By the way, I found this "variant" on my two 105.003 Ed White, one from 64 and the other from 65.

It should also be mentioned that in much more recent Speedmasters, such as the Speedymoon and the 'Holy Grail,
the crystals originally are unmarked ...

What do you think?
Could it be an A1.2 variant?

Have a nice day.

To be honest, it's hard to say much about the logo based on your pictures.
If this would help you in any way about how to catch the logo: try to do something similar to Ash picture - black background and source of light from the side. The camera doesn't have to be close to the glass, as it will be easier to catch sharp image from some distance.

It seems to be an A2 with longer and flat feet.
Here, for comparison, is a picture of an A2 logo:
