They were second tier models???
Because Columbus didn't have any tubing stickers that said SL/SP???
Like this maybe ?
or this...
Columbus and Bianchi like most companies never mentioned what the forks and stays were on their bikes with only the 3 main tubes made of a premium tubing. TRETUBI for example.
During the 60s and very early 70s, quite a few French bikes came with Reynolds 531 main tubes and Durifort forks and stays -Zeus too. They had Durifort decals on the forks.
BG, I think that the real reason was that frame tubing stickers were more of a marketing tool than anything else. Back during the bike boom, a number of British makers made frames with the 3 main tubes straight gage Reynolds 531 while the rest of the tubes were who knows what.
Bike buyers in the US became aware that a bike made of Reynolds 531 tubing was special. Little did they know of all the different Reynolds decals and what they meant.
I guess that Formula Two will remain a mystery.... (but I like your idea that it was probably a blend of Aelle and what have you)
Same thing with Bianchi Special Columbus tubing:
