i just got my dads norton that he has been restoring. im not sure if it is a 1964 atlas 650,700, or 750. the frame and gas tank have new paint and all crome parts have been recromed he bought new used parts and had them recromed i have the oringinal parts but they are not recromed. the engine has been rebuilt and i have to but the carbs. and pipes on. also have to hook up wires and gas and oil tubes. the serial # is 20 /111 250/ p any help with what the numbers mean would be helpful. and would you use old parts or use the new old parts that have beeen recrommed. i will be keeping the bike just wondering how you would handle the crome parts thanks fro you help mike

20/ means atlas therefore 750 P means plumstead the factory location where it was assembled.

thanks for the info
