The mechanism doesn't look too worn, it's almost as if the siren hasn't been used up too much.

There was another inactive single head Super Sirex located in North Canton, OH that was removed in 2016. It was on top of a building like the one in Hamilton. It's hard to tell from the picture but this one appeared to be single tone.

Also, the one in Adrian MO is actually 10/10 port like the one shown in this thread. The sirens in Madison WI and Toledo OH are 9/9 models.

The ones in Toledo and Holyoke also have rotators, but they've either been shut off or died. From what I can tell the 9 port ones are 50 HP sirens, where as the 10 port ones are 40 HP. If you compare the two the 9 port ones look a little bigger, at least to me anyway. The one in Dane County, WI was confirmed to have an actual 50 HP motor and was installed without the rotator.

It doesnt matter what the ports and motors are. In fact, the super sirex did have a 50 horsepower 10 port variant in Indianapolis, and the one in holyoke is a 40hp variant. Chicago had some 40HP variants too, and they were also 9/9 (confirmed from a dubbed audio in a federal signal ad)

Way cleaner in the table than I expected. My expected rebuild may just be a repaint and regrease, that would be incredible if it happens that way. . Going to doublecheck wiring insulation also, ages and cracks sometimes. Just doing what I would do for an old schoolbus. Those are what I really like to work with.

Should be interesting to see the old HOR siren ads his son is sending to me.

I have a 40hp 10/10 port siren like yours from Phoenix. Both motors are Westinghouse brand and the siren is in excellent condition. I'm pretty sure the 10/10 port siren is a lot louder than the 9 port, the rotors are a lot wider.

These things have shown up having very odd port ratios. It wouldn't surprise me if there's a 7/10 Port Dual-Headed model out there somewhere.

There were 7/10 port dual head Super Sirex models. There is (was?) a video taken at an auction in Phoenix AZ up on youtube. I don't know where it is but there was a dual head sirex that looked like it was 7/10 port. In addition to that, I have heard that there were also 8/8 port single tone Super Sirex's and maybe 12/12 models too. Here's a picture of one on a dam somewhere in California that almost appears to be 7/12 or 8/12 port.

I have no idea if it's still there since the streetview was last updated in Dec 2007. Someone who lives near it should definitely go check it out though.

I just looked at pictures of both and yeah you seem to be right. I had no idea there were that many variations.

The two at imperial dam are still their. In a drone video from 2017, you can see the white one still their. It also looks to have rotated, because in a picture of it from 2008, shows it in a different direction.

A fellow siren board member brought this to my attention. Many thanks.
