At that time, there was no AB yet.
Looks like an A frame & fork w/o eyelets.
Fork crown is like A
It has a plate BB shell (Bocama), so it's A
If it had a cast (Roto) bracket it would have been AA.
A has long dropouts, AA short dropouts (at least the later ones, depends on the age and the year Campagnolo started making short dropouts).
AA would have had a butterfly chain stay bridge (X shape, nut round like this).
I think the top tube cable guides are a bit odd. Can't remember that I saw these before. Maybe I'll see some more on Sunday.
