As unworthy1 correctly pointed out, the headtube does not appear to have been repainted, probably because the amateur who repainted the bike didn't have the means to remove and reinstall the badge. In person, you can tell that the headtube has a deeper, glossier, more durable paint job than the rest of the bike. And of course, it's a slightly different color than just plain rattlecan red.

As for the headbadge, I've checked the inside of the headtube and there is no sign of other headbadge holes. I suppose that the bike could have been originally unbadged or had an identically sized badge, but from the looks of it, this badge has been on it for a long time, if not from the beginning.

The fork is definitely original. The steerer tube has the same original magenta-ish paint that the headtube has.


Since the original post, I've installed a new headset and had to cut down the fork crown race from JIS to ISO, so this is looking more and more like a Japanese job.

I've been going with the story that this is a Japanese ItalVega, clearly not Italian or from the Torpado factory. My theory is that it is potentially a missing link between ItalVega and UniVega. I'm guessing that Lawee's contract operations had already moved from Italy to Japan, regular UniVega production models hadn't been set up yet, and ItalVega headbadges were in overstock, resulting in this rather unique ItalVega-badged Japanese bike. And discounting the 'G' prefix, the mid-400k serial number seems to be in line with the known production history.

That's the story I'm sticking to anyway (until some better story comes along.)
