Pre A is Vendome, because Panerai introduced the lettering since 98, with A.
So A is 98, B is 99 and so on.
Pre A is 97.
Not Pre Vendome.
BUT it is true that the Pre A ( Pam 1, 2, 3, 4, 6, 7, 8, 9, 10, and 21 ) take a lot from Pre Vendome.
We can even say that the 21 belonged to the Project Slytech, like the 36.
As for my new Leica, no, not on these pics...
The sad thing is that I stocked 14 reviews somewhere in my Computer, and that I lost 8 of them...
Best,
