Hey folks, I was trying to find some info on the bike pictured below. I found this site via google and have been climbing through page after page, very interesting and well informed stuff on this site!
Anyway, I was hoping someone could help me out with the identification of this bike (make, model, era? Is it real or replica?). I was visiting my in laws in Chicago a few months back and stumbled across this. It was locked in a gate and the sidecar was obscuring the engine cases so I couldn't really tell what it was. I went back to see if I could find the owner to have a better look but the bike was gone. I've stumped my father, a hardcore motorcyclist of 40+ years. Any help would be great!
