This auction brings a LOUD SIREN from the Monroe Timer Co., Inc., Bronx, N.Y. The Model S12C SENS-O-MATIC CYCLONE will fit any 12-volt car or truck application. I bypassed a little box inside, applied 12 volts to the circa 1970 Cyclone's positive and negative leads, and out comes LOUD! With its six-vane spinning rotor the Cyclone sounds like a 1950s police siren. If they weren't testing the new emergency horns every few hours in our town, Havre de Grace, the 911 board might have lit up. These horns are illegal, except in parades and car shows and other places w the ladies and kids love things LOUD. Low starting bid. PayPal only (no checks or money orders accepted) will ship US Mail anyw in 50 States for $12.00. We ship weekly. We are emptying the Biller barns, please see our other listings. Thank you.
