I bought this approximately 1975 Centurion as a project. It had been neglected in someone's back apparently since it was new. Surface rust, original rubber and plastic destroyed by the Arizona sun.
I had the frame and fork powdercoated bright green and the crankset, brakes, levers and stem done in mirror black. Spray painted the seatpost, front derailleur and small bits in gloss black.
Cold set the frame to accept 8 speed spacing and added green accessories as shown in the pictures.
Rides very nice and I even got away with parking it in my living room...well at least for a while.
