1939/1940 Horn Suppliers

[GaryU.]

My son picked these up in St. Paul, Minnesota for me and brought them down on Turkey day. Seller used to have a '39 Mercury and had this extra set of horns just in case he ever needed them. There was no paint showing as they were covered in years of dirt/grease etc. so I spent the morning cleaning and adjusting them back to good working order. When I took the cups off I was very happy to see the the inner workings looked factory fresh, didn't do more than clean the contacts. I've seen Spartan-Jackson horns and was curious about other horn suppliers like these "Schwartze". Were they indeed a Ford/Mercury supplier? Thanks, (Bet Kube knows!)
