Oh, and for what it's worth, I am unsure about the accuracy of the statement "all main tubes crimped". I've seen the top and downtubes crimped, but not the seat tube. That doesn't mean there isn't one out there, of course, that would prove me wrong

Just to update with better info. I have never seen those Profil Cx frames (Supers or Mexico/N. Mexico) with crimps in the seat tube; only top and down tubes. ESAs with main crimped tubes start late '86 (for 1987 model year
Seems to be some other info that does not equate regarding years for some models mentioned; no Nuovo Mexico until c. 1983 model year (frames made in '82-'83). I know of no crimped production bikes for 1980 model year or 1981 for that matter, but always hard to account for model changes occurring during a year after the catalog is published.
Saronni rode a "Profil" style Super in '82; 1982 (September) world champ bike is correctly id'd with "Super" on the display at their museum; features confirm it to not be a N. Mexico. Mexico/N. Mexico never had any inside crimps or indentations inside or out based on my prior bikes and another friend's bikes. Not sure if N. Mexico ever had just 2 downtube crimps, but '85 & '86 model years definitely had the 4 crimps in the down tube.
Look at chain stays for stamped "COLNAGO" which occurred c. late 1981 for the model year. I had a Super (no crimps) c. 1981 with unstamped stays, and no long crimps on the insides except the indents near the front @ tire and chainring indentation. Even on post-'82 the "COLNAGO" stamped stays were not always present.
