Thought you guys might get a kick outta this one! Built this one many years ago! It’s a Schwinn occ stingray frame,seat,and bars combine with a Honda xr80. It’s fun,fast,very stable and reliable! Always a summer time favorite!
That looks pre AMF ( they bought both Shelby & CWC in early 50's ), Shelby pre & postwar of that frame look alike so I don't know and don't know if anybody has figured out the Shelby #'s so I'm just going with 40's, maybe somebody else can narrow it down.
