What is this?

Looks like some kind of HOR rotational siren. I think we already had a discussion over this siren somewhere..

How long ago was this discussion? I've never seen this picture or this siren.

I'll have to agree on the rotational bit. Two rows of ports, could be dual tone depending on chopper.

Number 4. Looks like a federal?

Number 4. Looks like a federal?

Looks to me like it could be a knockoff Model 5/7.

HOR used housings with louvres close together like #4 and so did Decot. Hedberg had something similar with only one louvre on the top of the housing.

These look like Omni-Directional HORs.

Could it possibly be a Decot housing? The pole mounts on the smaller one look like Federal's.

I think this is somthing like my towns old siren that was taken down when the Tbeam went up.
