Looks like a Universal Security Instrument siren. These sirens are not hard to find. If the motor is relatively flat on the top and bottom, it's 110V. If the motor is perfectly round, it's 12 volts.
Yes it does sound nice with 110 volt, well not what I was looking for so I would love to trade it for a hand crank siren for the wife's golf cart, or just a deal on a hand crank, shut me any deal 2175160565 text
