just for skiddles and grins there were a LOT of re-brands (ie: ALANs sold as Guerciotti, and etc.) which you may like to peruse in this lengthy thread (post #71 has "the List" of all the re-brandnames we have complied, 67 names so far)
I try to ID which examples were CX or Carbone or what other distinctions they have/had.
Shout out to Lattz who replied above and has been a major contributor of pix and details to the thread, as well as non-fixie and his pal in Benelux fabiofarelli
