The rear hub is labeled "F&S Torpedo" and has the number "51" and the letter "M" stamped on it. Tires are labeled "700x32C MICHELIN 28x 1 5/8 x 1 1/4" (2 sizes on the sidewall of the same tire...what the heck?@!). The rear wheel spins, pedals and brakes properly..i just have no clue how I'm meant to shift gears without a derailleur (or what the heck derailleur is made for a 3 speed). I'm kind of guessing the "51' on the rear hub is the Year.
