Thunderbolt 1000 or 1000T?

[Thunderboltlover]

I was down at my grandparents house about a year ago and happened to notice a t-bolt as we were leaving. A couple weeks ago we went back. I got some better pictures and some videos of it. There is one problem though. I do not know whether it is a 1000 or a 1000T. I have asked the fire station cheif and he does not know what type of model it is. I would have asked him to growl it but it is a volunteer fire department. They also have a STH-10 and a Whelen vortex R-4. Alot of sirens for a town that small. Here are some pictures.

a 1000 and 1000T look identical; the only way to find out would be to either activate it, or look on the components for the ID/serial # badges.

You are attempting to link a picture directly to your computer, which will not work. If you do not know how to post a picture, you should read this guide wrote by Justin.

The control box tags aren't always the best indication of the actual siren head model. The 1003 on our campus has 3 control boxes and one of them uses a box labeled 1000.

You could also get up to the projector's level during a sunny day on a nearby tall building, and look down the projector. Normally, a 1000T has a little vertical divider in the middle of the port opening.

But of course the most simplest way is to test it. Even if the station does not do a noon blast, go to the station before noon, and then ask them to growl it at noon, so any member of the public will just regard it as a noon whistle, and not a fire call.

Does your county test right now?? Could just have them activate it then?

Well, as I said they arent ever there its a volunteer fire station. They get the firefighters buy activating the STH-10.

My Detroit Thunderbolt was a 1000 but the chopper cap has the divider. Pic Below.
My Skokie, IL 1000T has the rotator tag that states it's a 1000.

So maybe in 1952 they had no divider, but when the 1003 came out, they probably changed the cap to be used with any siren. and tapped the extra holes for the 1003 when needed?

The Thunderbolt chopper assembly I have uses a single rotor with a dual tone cap.

could be. that looks sand-cast, so using the dual-tone cap would mean they only had to maintain one set of tools.

Now that you mention that, the chopper assembly I have has the extra drilled and tapped holes for the solenoid bar, and I know it didn't come off a 1003.
