Testing a magneto horn

I have a decent magneto horn that will never use since my cars have generators. I would like to test it to confirm it works before offering it for sale. Any hints on the best way to do that using my car?

One wire from the mag to the terminal on the horn. Ground wire from the horn body to the car body/engine/frame. Adjustment screw is in the center of the diaphragm.

The adjustment screw is in the centre of the diaphragm, deep in the trumpet. I made a tool to do the adjustment , consisting of a socket wrench welded to a steel tube, and a T handled screwdriver with long shaft to drop down the tube.
