AUTHENTIC OLD BRASS DUAL AIR HORN ORIGINAL UNRESTORED

Description

AUTHENTIC OLD BRASS DUAL AIR HORN ORIGINAL UNRESTORED.
I don’t know if it is train, truck or ship. I cleaned out the diaphragm and hooked up a 1/2 inch compression fitting and fired it up. I let it sing for an hour. It works. It was set up with a pull chain to activate it. I polished a small piece to see it is brass. I ran a magnet over it and it does not stick to the horns or the diaphragm housing. It does stick to the mount brackets. They are iron or steel. It is super clean with vey little physical damage. I think it would polish up beautiful.
