This thing showed up yesterday morning on one of the local ad pages. They guy was giving it away. I was first caller but more than an hour drive. I never got a second call back. Maybe someone offered him some money.

Still wish I knew what it was.

It has a battery cable for one connection.

Perhaps some kind of Civil Defense Air Raid siren??
maybe a mobile one ... that would fit with the car battery connection ...

That's where my mind wandered too, especially looking at the
noisemaker end (probably not long/low-freq enough for lighthouse duty).

So it this an amusing puzzle with an answer? or a continued curiosity?

Is it a horn, or some kind of funneling device? Grain, or dry product, perhaps…? Covered with corrugated metal it would be a darn good replica of a Mercury capsule..
