Thanks for scanning those. I see that silver book also confirms that the town and country switch could be used to control the seashell horns on trucks, something not stated in the 41 accessory brochure. I did recently see a T&C switch on ebay but I held off because I was not sure that they were for the 41 trucks.
Yes Gman, I would like to see a photo if its not too much trouble.
The trumpet horns are without question more attractive, and I would certainly put one on my truck if I was not going bone-stock. There is one on ebay now listed under 1939 chevy horn which might be worth watching if you want one.
