I could have swore I saw this badge on a Single Cylinder Excelsior Motorcycle that looks alot like a bicycle. I believe there was a site somewhere also that shows the different badges for the years. The back looks to be brass?
Looks like there may be a silver paint over the front- I did not try to clean or restore it at all.
