That's no Federal, but it could be a HOR, Hedberg of some sort, or a B&M.
There's literally a Federal logo on the top.

It's one of the blast proof Federal indoor warning sirens. Basically it is a Model A or D with a different cover on it. The US Navy in particular liked them for use in ships. I saw one of these in the USS Alabama many years ago when I went there. Almost wonder why it would be in a mansion. Fire alarm perhaps? anyways, nice save!

Could it possibly be a model 66?
Nope. The ports are way too small to be a 66. They are much bigger, sharing them with the Model 28. The 66 would also (most likely) have a chrome bullet-shaped cover on the back as well. I believe the AX uses the same rotor as the Model A
