I decided to try compiling a list of serial numbers after 1960, if any of you can help make it more accurate in anyway please provide me with any info, eg; if you have an old ccm bike that fits into 1960+ and you are certain you know when it was built and can provide the serial number letter please do so! If you have any other "dating" suggestions feel free to let me know!
