I've noticed also a wide variety of versions in the decal set - including the "Inter 10" decal on the top tube.
This example looks like the gold "Inter 10" decal on my top tube.
This one, albeit similar, is a bolder (demi) font in white rather than gold.
This one shows a completely different, sanserif white version of the "Inter 10" decal as well as a completely different variety on the down tube.
