l suspect that it is a repro sold by JC Whitney, Western Auto, Sears, etc. None of the original horns had a bright bell, they were all black.

As to the voltage, even the new 12v Spartan horns that A&L sells are marked 6 volts. The one I bought came with a slip of paper saying that even though it was marked 6v, it was really 12v. They only make the ID tags that say 6v.
