Extremely Rare Sirens

[Hacksaw]

Here's a rare one, made by Hedberg. I don't think this siren exists anymore:

Ah, those were the days. Going out in our Sunday Best to such establishments of A. Hirsh & Son's Appliances, Geo. F. Heublein's white goods, and Chas. Parker Haberdasher. Then for an egg cream at the soda shop until we all piled into the family Studebaker for the ride back home. Hasn't it been a marvelous day, dear?

and yes, my wingtips are polished.

It looks like a six-port siren running on a speed-increasing pulley system.

Whatever happened to that photo of the Hedberg dealer's table at that 1930's trade show? It showed a variety of Hedberg sirens from small to large.

A few ACAs appear to be quite rare:

Allertronic 5000 (none currently exist, a couple of them were made and scrapped)

[SoundOff]

Thunderbolt 2000 (blower driven by a 2 cylinder Onan gas engine) One used to exist in San Dimas behind the fire station on 1st street but was removed around the beginning of 2009. There appears to be another one by Overhill Elementary School in the Windsor-Hills area of Los Angeles (same style pole and mounting) but I have not been out in that area.

There's also the six-horned siren by referred to as Toshibas (see my avatar) used by Southern California Edison for emergency alerts in the communities of San Juan Capistrano, Dana Pt, and San Clemente which were located near the now-closed San Onofre Nuclear Generating Station. Those were replaced by a new Whelen based system in 2007. I have not seen that style siren used anywhere else.

Cosgrave.

Big Bertha, the only-of-its-kind beast that preceded the Victory siren.

There is the Heath siren in the recent thread and the other Heath that was on the Ferry Building in San Francisco.

The FS Bumblebolt (Only two I know of) and rounderbolt (doesn't exist anymore or still does just with the standard square horn).

[ncovert]

The rounded T-bolt always had a square horn. The blower and rotator box were slightly rounded off at the edges. I don't think any were produced; it was probably just a prototype spotted in an old advertisement (Companies tend to show prototype models in advertisements for some obscure reason.)
