In the CR archives I found this interesting fact in a post (dated 23
Nov. 2002) by Dave Martinez: "For what its worth... According to an
early 50s German H'O'MANN catalog the Cinelli line-up is: CINELLI 'A'
(Riviera), CINELLI 'B' (Mod. B) and CINELLI 'C' (Mod.SC)." It seems
strange to call your top-tier frame "C" and your third-tier "A", but at
least it leaves room in case a new top-tier model is introduced, to be
called "D"!
