A nice looking horn, its identification plate is very clear. It works great, checked with battery. Will work with 6 or 12v. This must be a very early horn, because it has screw wire connectors to take a wire ring, not the usual bullet connectors.
Mounting holes are 2.1 cm on center This might be from a REAL early Honda model. Collectors if you know about this type of connection, this may be just right for you.
