Vintage Hadley Dual Trumpet Air Horn Chrome, Pump, Tank, Switch, Bracket 1950's

Vintage used Hadley dual chrome air horn in good condition. The horn is tested and works. I did not test the air pump, tank, or switch. It is a 12v switch according to what my grandfather had written on the box.

I included photos of the lengths of horns and bells. Guessing  from the mid 1950's from some research.

I am guessing that my grandfather Reconditioned the horn and tank many years ago. No idea about the pump.

Please see photos for parts and condition.

This part comes from my late grandfather's small rebuilder's shop that had been around since the 1930's. They threw nothing away.

Thank you.
