Can anyone identify these sirens? (again!)

[Daniel]

I know this was on the board earlier, but since there are always new people around, I thought that I might try it again. The top photo shows the siren in Tangent, Oregon, on the hose tower of the fire station. It has three horns, one of which is falling off, and it looks like Sterling may have had something to do with it. It sounds one blast for fire calls, but I have never heard it. I have never seen another one like it. It looks similar to the siren in the bottom photo, of which there are several in Oregon. This one is in Gervais, has nine ports, and some of the others also have a de-icing floodlight.

How interesting, Daniel!
Thank you.

In first photo, I think siren would be.tter withouthe "plenum" surrounding the stator ports.
I presume there would be cancellation occuring inside that common chamber.
Better to have one "megaphone" from each stator opening, like the 2t22.

Also, round megaphones are better than square which are better than rectangular.

(Would be interesting if megaphones could be tuned to the siren's peak pitch!)

Years ago I wanted to make a siren whose stator port air also blewhistles tuned to the peak frequency!)
Imagine that monstrosity!

In 2nd photo I like the unscreened stator and rotor intake.
Probably not a good idea, but I like it.

Do you knowho made these?

Love seeing these unsusual designs.

That's what this post is for.

I remember that some people accounted these as very old Sterlings or Darleys. The air-slots are very indicative of Sentry's wide-used practices of using air-cooled motors.

The second one looks like a 7V8B to me.

I have looked into this myself, there is one of these at the Foxburg Fire Department out in Western Pa. It is an early Sterling vertical siren, the first one is the same as the second siren except that whoever owns it made horns out of sheetmetal. Not sure what is sounds like, it looks to be an 8 port siren.

The siren ontop of the Bridgeport, CA firehouse looks similar to that one... But inverted, and with more ports, and with a goofy-looking cone over it. Fellow boardmembers who commented on it think the Bridgeport one has the chassis of a Fedreal 5 or 7. (discussed in this thread): http://airraidsirens.com/forums/viewtopic.php?t=470
