Since he was 3 years old and pointed out his first 5t my son has become the air raid siren savant. We drive around sometimes looking for firehouses to identify new sirens.
While browsing a very expensive antiquities shop he somehow discovered this at the very back of the store. It didn't work but the owner was so happy to see my son excited over it that he gave it to us! Actually... He was required to "pay" one piece of gum from the candy store.
I was pretty surprised when he didn't know the model honestly so we don't know what it is. Currently we have it disassembled in the shop getting it cleaned up. Any idea what I can tell him this is?
