My 1975 MKIII was titled by the original owner in Pennsylvania by the frame number in 1975. It is stamped on the neck of the frame. In my case, the number is 850F1296**. It passed the title inspection when I brought it to Nebraska by the DMV just fine, because that's the way it was done from the original MSO - not the engine number. That's somewhere around the time they were doing away with just engine numbers on titles. My 72 is titled by the engine number. Norton tried to stamp some little Globe emblems in between the 850F and the last number. They barely show up. Nothing suspicious about that frame in KC.
