Hi gang, I'm not a Bianchi specialist either, but I have owned a few, over the years. The Team Issue had no head badge, and only said Bianchi on the down tube. The very nice 1965 original Specialissima I recently bought has the very same Made in Italy decal as the one on Ebay. I have noticed that the location of some of the decals change over the years, that may just be the person installing them.
If it were my size I would ask the seller what the serial number was, the manufacture date is in the first few numbers.
