Thanks for giving, gents! However, this is starting to look as muddy as it was before I asked.
My crank has the non-engraved logo fairly close to teh BB, not out near the chainrings as on the second C-record shown in Velobase. I looked at the early C-record catalog, but I haven't yet tried to trace the pattern through. I also FWIW have a script Ugo de Rosa pantographed on teh drive side arm.
