The first bike is a 1963 Flightliner, standard model. 46301 is the catalog #, 502 is a code used by Murray to ID it as a built for Seras bike. The second one is around the same era, but generally not stamped with any decodeable #'s. -Adam
Thanks Adam! The guy I got it from was told it was a '58 but we both thought otherwise. And yes Pick they are; the guy added them so he wouldn't have to worry about dirty spokes... They are coming off the bike for sure tho
