·Ciao Gino,
I missed the latest posts of this thread. I guess this 145.012 is simply 26.552.325, produced 18.10.1968 and delivered to USA. Same for other known 145.012s NASA in the same batch of 10 units (26.552.32x).
To my knowledge, 20.552.xxx does not correspond to a batch a calibers 321.
Ciao Greg,
even to my knowledge 20.552.3xx shouldn't match to a batch a calibers 321.
But the fact is that from the photo of the caliber 321, from the Smithsonian, the serial number is just 20.552.325 and moreover we also have 2 different documents, from NASM and from Bienne, that affirm this
Stafford #76 caliber 321 (from Smithsonian)
NASA Chronograph list (from NASM) extract
NASA Astronaut' Speedmaster (Omega Bienne)
Ciao, Gino
