Federal Signal RX Siren?

[Kaleidowolf135]

So I managed to snag this thing for $65 on ebay (shipping included), and there was only two at the time. It's in unknown operation, but I bought it to restore, with one problem.
There seems to be NO documentation of existence of such things listed on google or ANY search engine I tried! Could this be a siren we've never seen or heard of before? The tag DOES say RX on it, but my question is, where is the documentation?

Does anyone know anything about this? It's going to be on it's way to me as soon as PayPal authorizes and sends the money to the seller.
There's a second one here: http://www.ebay.com/itm/380458609016

I saw that and didn't buy it for one reason...I don't know what it is, and that will make it a PAIN to restore.

That thing looks cool, I just won a siren too.

FSThunderboltfan1000 sent me a siren manual, turns out this is basically a coded model L! How interesting!
Now isn't that something to argue about, "Oh you have a model L? Well jokes on you, mine is coded!"

By looking at the ebay pics I don't see how it can be coded.
I don't see any mechanism on it that would do that.

What does that exploded view show?
In the second pic down on the auction page I'm looking straight through the air intake tube and I'm seeing the rotor. That's why I'm saying I don't see any coding mechanism in the photos. I don't see how an air valve, solenoid and linkage could be stuck into that air intake tube and not see it in the photos.

I've been misleaded then.
Oh well, I guess I got a siren, right?

[Kaleidowolf135]

As an update, the label was printed today, and the siren is on it's way as it will be dropped off tomorrow.
I'm super excited for this one, and I'm sure a few people here are too

Some of those sirens had a weighted damper that would shut whenever the siren was not drawing air, but reopen when it was powered up.

Poor mans coding siren.

I might have it backwards, I think Federal made a vehicle siren that would pulse automatically whenever powered up. It was done by air flow and had no solenoid.
