I bought this bike about 20 years ago at a church sale for $15. It came with an Apollo 13 bell ringer on it so I figure it is a least a 1970 model. My daughter used it as a child and now her son will soon be using it. As the photos show it is a folding bike with seat and stem extensions long enough to accomadate an adult. It was made in Italy and the closures are in Italian, and the hex heads and bolts are metric. The seat is leather and has the name "Dal" on the back. I've search the internet but can't find any information on it...anyone here ever see one like it? It's a very cool bike!
