1920's German motorcycle handlebar mounted horn button; I don't know the maker.It is missing one of the nuts for the strap (easy to make) and is otherwise complete and ready to use. Made of brass and steel.I can post this, and I accept PayPal.
An original brass Klaxon horn in excellent original condition and full working order. Complete including correct Klaxon bakelite cable terminal connectors, screw top missing on one. Buyer pays shipping cost. Probably too heavy for overseas posting.
