Do 3T”22” prototypes (7/12) sirens exist?

Hey guys, I wanted to ask if this particular siren actually does have a prototype that physically exists in the 7/12 port variant? after stumbling on this random video it shows that they were actually models that existed, but I’m curious has anybody filmed one?

I’m probably just hallucinating at this point, Also these are screenshots from the video

The 3T22 in the picture is located in Geary, Oklahoma, and it is a typical 3T22 with a few horns missing. The "7/12" 2T22 was only concept art, and never existed.

Ahhhh ok well I know what to get from Edaan now, At least that confirms that they actually don’t exist, although it does make me wonder would it be possible with a 15 hp motor and the rotor and stator sets from a STH 10/STL 10

This is the closest you’ll probably get to hearing what one would sound like. https://youtu.be/8kSKONAS5JA
