Autolite is a manufacture for Ford so it raises suspicion that they are original. I found one on eBay that said it was 6 volt and another on the internet that said 12. If you already tried it on 6 volts, momentarily try it on 12 volts. The old horns are pretty robust so I don’t think it would hurt to try it.

Good Luck!
