Neat! Thanks.

What manufacturer? model, voltage, etc.
Details, prease.
I don't know enough to know.

My uneducated guess: Thunderbolts.
But how did bird droppings get into one?

Thank you,

[loudmouth]

it could be a Model2 they have the same size rotor.

I think that those are both from his Thunderbolt models.

[jerrylovessirens]

Those are both T-bolts

Joe got a single tone T-bolt, but he now got a dual tone chopper for it

Those aren't bird poo, it's corrosion.

Wait a second, I never knew that Joe has one of the rotors with a five-to-four port-ratio!

Those are the best ones, In my oppinion. Barrington has 2 of them.
on test day, tey sound 2 minute Attack, 1 min rest, 2 min attack.

Its a beautiful sound

Yeah, they do sound awesome. They have the same tonal ratio as the Hurricane MKII, only lower by half! Maybe that's the reason that I appreciate this type of Thunderbolt-rotor more than the ones from any other type of Thunderbolt.

Sure looks like small birdroppings to me! (And everyone knows I'm thexpert in that area!)

As though that rotor chamber aligned withe opening and they got inside.

The two Chinese sirens I saw, one of which I molested (touched),
close their stator ports.
It felt as though a magnet pulled the rotor so that the ports were
always blocked.
Neither of the sirens had any screening.
Also, none of the Lion King sirens has screening. http://www.lksos.com
