John,
I'd say there is a possibility you have an Italian Masi, indicated by the "M55". I don't know what those other numbers are. Where do they appear. They could be non original (bike liscencing or who knows) but The Italian Masi will have no other ser. numbers. Is there a date (mo. and yr.) stamped on the steerer of the fork? If so, you most likely have an Italian Masi. With a few good photos, I could probably tell for sure.
