I finally looked at the ebay link. Although I am not a "Supertigre expert" I believe that the engine is the combat version. It is lapped, not ringed. I think this version was replaced by two specialized models, one for stunt and one for combat. Most Supertigres of that day had the "V" on the crankcase. I think it was for looks, not part of the designation.

About 10 years ago, all Supertigre production was moved to China. I don't remember if the entire operation was sold or if MR. Garofali retained ownership. I understand that the quality standards have been maintained.

IMHO it would be a good engine for general purposes but better for a collector. Probably not good for stunt.
