Hey there,
I just picked up a Mirage from a local Police auction. There is a sticker on my frame on the seat tube, right underneath the main tube, that states, " 1020 Steel, Tubes, Forks & Stays". I wonder if the quality of the frame in the Mirages changed during the model's life span?
I have no idea what vintage this frame is, (my first Motobebane), so any help in dating it would be appreciated. The numbers underneath the bottom bracket are: 3692828-701. There is also a "609" marked above the other numbers.
I have plans to build a beater fixie out of it. I have a Maillard track hub that will match the Normandy up front, a Stronglight T/S crank, and some 700c Sun rim's around here somewhere......
