Unfortunately there is no cool winged logo! And you are correct-the wheel does say 27 x 1 1/4. I found the serial numbers when the bike was upside down. They were right below the pedal crank. the numbers are: 517 473010 and below that: 1625789. I took a series of pictures of stuff like: the pedal crank with the words "aduprat" and "universel", the various logo stickers on the bike, the seat, the serial numbers, etc. Maybe tomorrow I will be allowed to post a link to the photos!
