That's an old Federal Enterprises Model A. Don't see many with the badge on the outer horn. The siren should work with 120V, it's best to check the bearings before running.
If it's an Enterprises model, it's from between 1948-1955. They're worth about 250 in good condition, I'd say.
Just a wolf, siren enthusiast and railfan.
