You are right, I made a mistake
If you mean a Sparton horn as found on GPW's, I wouldn't be in a hurry to swap with a Schwartze horn.If anyone has an original one...I have a NOS FORD horn to trade
Unless someone can prove they are correct on factory new jeeps on a wartime picture.
Faulty manuals and amateur written books have been proved to contain wrong information for many times....
Kind regards, Luc
