Horns! I love this thread becasue I love horns!!
I had an a-hoo-gah horn on my Jeep but I wore the damn thing out!! It's replaced w/an air horn now and it is LOUD. The a-hoo-gah horn that you can buy at Harbor Freight or at the auto parts store are very low quality. They don't even sound like the real deal. I do believe that the classic a-hoo-gah horns were motor driven (to give them that classic, deep throated AH-ooooooo-GAH sound) but I could be mistaken.
Here you go! Now THIS is a horn;

Now, while I love horns I will be sticking w/the stock Ural horn for my rig ... at least for the time being!
P.S. I know I'm new and excited and trying to catch up. If I get annoying by typing too much or too often or digging too far into the past just shoot me a PM and let me know. I'm very chatty and I apologize. Just excited to learn I guess.
