Junior long roll siren made by federal electric co. Inc. I removed it from a 1944 Mack fire truck that came out of service, siren and light both worked, obviously needs restoration but in great condition for 75 years of use. Comes with the side mounting bracket. Please ask for a shipping quote if your not 100% sure, I'm happy to provide that information to you before you bid. A great fire truck part no reserve on the auction.
