German WW2 Siren

[estokke09]

The newest addition to my collection, a German 1940 date stamped Jurk siren!

[Captain Dynamite]

Nice siren. How many ports?

[estokke09]

Thanks! 7 ports

[Captain Dynamite]

Ah nice. If it had 10 ports in front of the 7 ports it would make a diminished 5th interval.

I would like to see a dual tone hand siren.

I would really like to get my hands on 12/10, 12/9 & 12/8 port hand sirens but I think I'd have to get some custom made to achieve that. If I did, I'd use the ACA rotor and stator designs since I like the sound those make. As far as I know the one Adam Smith made many years ago from a Federal Signal 77GA siren with the 9/8 ports is the only dual tone hand siren in existence unless there are others which I've not seen.

If you would use the ACA rotors, you would need one hell of a arm!

[Captain Dynamite]

No the regular ones are to big & heavy. If I were to use full size ACA Rotor & stators I'd have to put them on a pedestal. I'd get smaller versions made with 20 centimetre ( 8 inch ) rotor so it could be held with both hands like a regular hand siren.
