Seems like I have seen one like this, but it would have been way back in the past when this was new, so memory is foggy. I'd guess this might be one of the early frames made in a Japanese factory for Ben Lawee before he decided to go with "Univega" and still had a stock of the Italvega badges. I suppose it's possible it's built by some Italian supplier other than Torpedo, but I'd still guess Japan (and I'd further guess NOT Miyata)...until proven wrong. What's the width of the BB shell? What's the size of the seatpost?
