Stainless steel model 5 & 7s?

[CABLEVision]

Being the DeLorean freak that I am, I can't but help ask if there ever was a Stainless steel model 5 and 7. I almost swear seeing one before and it would make since for a town near the sea to have one. I know lion king has a rip off of one. Any one else remember this?

The town of Concord, Michigan has such a siren located by the fire station. I believe that it is a Model 5. I don't believe they use the siren for fire calls anymore, but its still used for Tornado Warnings. However, the last time I was in Concord, was over six years ago.

What is all this talk about Lion King sirens I keep hearing? I'm confused, when was there ever a siren in the Disney movie "The Lion King"?

Someone please explain this to me, hehe.

Not meaning to get off topic but...Yikes! Can't Federal Signal sue them for making such a perfect copy of the Model 2?

Federal did make a stainless model 5/7 siren

You can't sue anyone in China since the Chinese government does not recognize US authority nor will they cooperate with us.

Why thank you for the photo. I would like to own such siren I wonder how many years these were produced?

Nope. The patents on basic siren technology expired many years ago and you can't sue someone for making a chicken-feeder enclosure, which Federal wasn't the only company to do; and that probably wasn't patentable in the first place.

I doubt the Chinese "ripped off" ideas.
They are likely original plans developed on their own.
If I were to design a siren, I'd do what was most efficient and cost effective - which would likely result in the designs we see.

Does anyone else make a single-tone siren which parks with the stator vanes blocking the ports closed?
Saves having a screen which also is an obstruction to sound output.
From whom did they rip off that elegant idea?
