Thanks! I looked up the "Flemings Pumpkin Run".
Pumpkin Run (flemingspumpkinrun.com)
Lookes like a great place to visit when I get out east again.
Re phase converter: Yes, a phase converter if large enough would run that big siren. But they're big and bulky. The new VFDs (Variable Frequency Drive) are the digital electronic version of those old phase converters and a very nice way to run 3 phase equipment off of normal 1 phase (house) power. And the price of them keeps dropping where it's just about in my price range to hear that old siren howl again.
It had been sitting in a shed in Wisconsin for who knows how long when we bought some other equipment from the shed's owner. He made another sale and the siren came home with me. The large rotor was seized up on the motor shaft and partially to the outer drum with the minute clearances involved. But after a lot of penetrating oil and other wizardry it finally let loose and the rest was easy. When it's operational again....I'll have to post a video.
