My roadster has no horn I need a Ahooga horn but I am picky about anything I add to this roadster. So I don't want a brand new, cheapo looking horn. I prefer to buy an older one. They usually are 6 volt. Will a 6 volt horn work with a 12 volt system? Some told me it will and some said no...

WHAT DID MODEL B HORNS LOOK LIKE?

Do I want to get the black steel ones or the ones that have silver metal with black metal (see photo #2 below)? I suspect the silver/black ones are more recent? But not sure... Any guidance appreciated.

In short, what do the really old horns look like? (how can I tell a really OLD one from a semi old one)

Below are a few exemple of horns I found on ebay, which would be the best addition to my hiboy?

all black metal - looks pretty old but in good condition


black with silver metal - seems newer ?


this one is advertise as a model A horn (is that true?)


Is one is OLD for sure! Model D (what year was model D?) horn


Any input appreciated.
