Hi T-Mar, many thanks for what you are doing here! I now have my two daily rides accurately dated, thanks to you. I picked up a very smart Centurion Super le Mans a few days ago in great condition but with a large frame, with the intention of swapping to a smaller one. Found the frame for a much older le Mans the next day and I am impressed with its smart brazed-on cable stops and chromed socks. There's one number, stamped on the seat tube, at the back and just below the pinch bolt B622. It was once a metallic red and bears the remains of a decal stating "Designed by Mitchell" and another "Guarantee". Might there be a clue? Photos below, and the Super le Mans that shares the same FD and RD is here: Centurion Super le Mans


It once was red metallic.


Guaranteed?
