Back in the day, Vespa and Lambretta were not the only scooters in the game. Just about every major motorcycle manufacturer tried to pull in some profits from the large scooter market in the 50's. One of those companies was TWN in Germany. They built the Tessy. A very few of these made it to the US, and it looks like one survivor is now for sale on eBay.
Obviously, beauty is in the eye of the beholder, but personally, I don't find the Tessy to be particularly pretty. Odd, yes, but pretty, no. This one looks like a fine basis for a restoration, if that is your thing. It looks like it is almost totally original. From the paint to the seat, it all looks old, but stock. On the other hand, it is missing the side covers, which could be a major problem. Certainly you are unlikely to find those in the US, and would have to search in Europe. There are quite a few bids on this thing already, and it is up above $500. Withe four days still to go on the auction, where will it land?
