Thanks to all who replied! As everybody has stated, the electrical requirements are going to take some figuring. I know these were located on top of buildings and towers to warn towns of incoming air raids. I believe they put out around 132 decibels so I know they're incredibly loud! I have seen the video 37Webbing provided and it is definitely one of the motivating factors in me buying the one I have now. The timing could not have been better as the gentleman I purchased it from literally found this one about a week after I contacted him inquiring about a genuine WWII air raid siren.
If and when I do get mine up and running, I'll be sure to post it for everybody. Thanks again for the information.

132 decibels will cause ear damage if standing by it...

As I said it shouldn't be a problem if you consult a qualified electrician. The whole world uses three phase systems for power distribution and industrial applications especially high load motors and the US is no exception. I imagine all you have to do is look in the phone book (if such a thing can be found these days, you know what I mean though!!).

I look forward to a video if you can make one!

In the 90's I lived in Wokingham about 5 miles from Broadmoor secure Hospital, They had these fitted and would sound them in the case of any 'Patients' escaping. It was procedure that they would test them every Monday morning at 10am. I recall the first Monday I lived there hearing the sirens sounding, I was more than a little concerned due to A.No one having informed me about the existence of the sirens and b,the cold war still being ongoing.

Yup, full-on goose bumps! Arms AND legs!!

Electrically to be on the safe side you need a vfd, or inverter, these can be set to output the correct voltage, frequency and even soft start the motor. From any input power.

Are they the aluminium type? They are very brittle and can crack easily being so old. I never had cause to remove the fins, but would suggest using easing oil such as WD 40 or better still Plus Gas, although diesel or paraffin will work at a push. You might need to allow several days to allow it to penetrate, and multiple applications.
I just thought, you have removed the tapered locking key from the bearing shaft haven't you?
