12 volt horn

[gridleak]

I picked up a Klaxon 5 horn marked 12 volts. this one has the reverse flare. My question is which cars of the 20s era use 12 volts?

Without going to early motor manuals, Dodge for one up till about 1926. I am working on a 1920.

Late friend of mine in Hershey had Model A horns labeled 12v & 6v. Asked how they 12. He said "do not sound good on 6".

The large end of the horn is connected to the horn motor and the horn tapers smaller towards where the sound comes out.

Ken I am glad you asked what is a reverse flare and not why.

I've seen plenty of horns with the "business" end smaller than at the motor end.
As for which cars were 12 volts in the 1920's - Dodge were and just about every non American car. Not sure about Chevrolet. I think Ford were about the last to go to 12v in the 50's.

Chevrolet was 6 too.
