Hi everyone, been learning a lot here as I continue to restore my gramps truck. Turns out a neighbor of mine has a 1952 5 window that I just saw/ found out about today! I didn't think there was another like mine in the whole city much less down the street. Anyway, I was looking at his today and noticed that his horn looked like a klaxon... Mine appears to be a clamshell repro. Is there a good source for rebuilt horns and is his an original or just something that was put on at some point?

Thanks in advance!
