The downtube transfer is interesting, its the first time I have seen the sans serif Masi (of the Vigorelli) typeface on one of these. From time to time thus font shows up incised into brake bridges.

My best guess is that this is an early bike, prior to deciding on the graphics. It may not have been painted in the USA possibly, part of a sample run. It was lean times back then for road bikes, everything that could be sold probably was.
