HI All ! I brought this home from the scrap yard thinking it was a Siren but with a 1" pipe feeding it I have my doubt. I was thinking if not a Siren then maybe some sort of fog horn? It does have spinning parts inside and I put air pressure to it but only got a hum out of it as I don't have enough air volume to spin it fast enough but it does spin, the horn is brass and the inside parts are aluminum and brass, so what do you think? Anybody know what it is? I can't find anything like it on the net. UPDATE, Old Gamewell Diaphone fire horn from the top of a fire house, you can hear one on youtube. Patented in 1910 and some are still used today.
