The biggest Campy-dealing pro shop in Bonn, Germany, sold non-fluted
posts like yours in 1990 as Campy SR, together with non-fluted
cranks. I have no idea where the logos were or whether the head was
polished entirely, as I didn't care much about that at the time.

Deleting flutes is easy and not a fundamental change - the flutes are
machined after the main post is done. Delete that step, and you have
a non-fluted post.

Could it be that Campy offered for the C-Record group both an aero post (for modern cyclists concerned about aerodynamics) and a round one (for old-school riders concerned about weight - the round one was lighter!). Shimano did at the time with their Dura Ace group. This is just speculation, so don't flame me, please.
However, didn't C-Record use an Allen-head bolt from the beginning? And yours has a standard bolt... unless that was changed.
Finally, all that stuff is OT, as it post-dates 1984. So my apologies to the listmaster.
Good luck,
