I found the Gran Corsa more intriguing. Those are even more scarce, nicer head lugs to my eye.
The subordinate models struck me as just curious overall.

There was the "bad batch" that Masi/Torelli did not accept and sold them off along the way, perhaps that was an attempt to expand the contract builder roster. Rumor was Euro-Asia painted them up somehow and sold them off.
they show up most notably with an outline M on the "melted" sloping crown shoulders.
