SOLD!!
Here is a really good original, all brass Rubes horn. Based on the circular mounting bracket, I believe that is for a late 1912 through 1913, but can be used on all years. It has both thumb nuts, a good front screen, an adapter and a rotten rubber bulb but it has a brass ferrule still attached. This one is in really nice condition and has a clear, stamped "Rubes" on it. Take a look at the photos.
The price is 245.00 and includes FedEx Ground shipping with insurance in the USA.
