Hello all. It has been anumber of years since I was last on this site. I still have my orgional johnson rifle,sold the sporter that I was in the process of reconverting to military, to a Marine friend who finished the project. In the meantime I just finished another sporter (reconverted back to military) for another friend and was seeking information on the serial number. As I recall from years past there was someone who could check those without letter prefix's. the number is 8868. Thanks RMW
