I hope it's OK if I jump in here, since people are talking about brackets. Can someone help me identify these horns? Got them from a used parts dealer. I have a 1953 3600, and I was thinking of using them on the firewall as shown in the Chevy Accessory manual.
But I am baffled by the brackets. From a car? BTW, note that one says "LO" but the other has no similar ID. Also, one wire seems to go to a screw post, the other horn it comes out from under the case.
Here they are:
