You might try posting an ad in the "wanted" section of this site: https://www.fordbarn.com/forum/forumdisplay.php?f=17 You could also use the search feature for horns in the "For Sale" section. Click on "Search" in the black bar at the top of the page and then click "Go Advanced". Put in "horn" for a key word and in the "Search in Forums" box enter "The Swap Meet/For Sale/Model-A". Good luck and welcome to ford barn.
