I live for the CABE
I have another possible extension for the "BF" acronym. I know nothing about this Campy hub ID, but if info came from there from an "expert," I'd take it with salt.-----
posted a link to this discussion over at BF and within a few minutes got a response from the foremost authority there on Italian fittings of this era
he wrote that it was obvious to him that the chrome had failed and someone went at the loose plating with a wire brush/wheel
this assessment fits right in with the heavy scratch marks visible in your excellent pictures on the alloy flanges
those marks are far too heavy/numerous to be ascribed to "normal wear and tear"
absence of Campag markings on the axle parts is likely due to the whole axle set being replaced by the wielder of the wire brush/wheel
since you will not be disassembling it reckon it shall simply remain an oddity
I've seen you over there in the same capacity as here and I appreciate that. But there are people over there that are.... Hmmm... Lost in the minutia of self?... Shall we say?
MANY of them. A controlling minority of self absorbed clowns.....
