The Siren Board

I found this siren in a antique shop in 2018?? it works perfectly, I tried selling it but I'm happy I didn't, i also have a clean version I found of it online, its very loud for 120V!!

Woah! Those are quite rare, hold on to that. I don’t think there are many of those. I saw an original Federal Electric Alarm siren (they are not called that) from the early 1920s in an auction. As soon as it was up it got snatched in like an hour!
