is it not odd that instead of ACORN there is a HEART??
Precisely.
The Colnago Super/Mexico/etc all had the clover.
The Colnago Sport of that era had similar concave seat stay caps to the early Colnago Supers. Typically had grooved bottom brackets, and heart shaped lug cutouts. Lacking the clovers makes it slightly less definitive, but the bike above has enough sport features to make that seem plausible.
