Well what other 8/12 sirens are out there other than ACA's products?

I think Grifco made a few but there isn't enough videos to know. Since we know that shipments of Cyclones were made to Australia and someone has supposedly found photos (which I hope are posted soon ) the Cyclones sound like the most plausible explanation. I have a feeling they sound different because of 50 hz.

Was guessing a foreign company was behind it. The sirens in the video sound pretty similar to Cyclones, however no one's confirmed that they are or aren't Cyclones so I guess we'll have to wait for a little while to get our answer.

Alright, took long enough, had more important stuff to deal with.
These are not the clearest images ever, nor may they be correct. Please do not get upset, this is speculation, as this is literally the best photo we ever got. I believe the Cyclone more than the Tbolts.

PHOTO IS FROM MID 70's.

Hmm- maybe it is just baseless speculation. The "Cyclone" looks like a flat box on a pole. The only picture that is somewhat clear to me is the first "Thunderbolt".

I hate to say it but these photos aren't evidence of anything at all. The bits of yellow are unshapely blobs that could easily not even be sirens. I mean, that's been stated already. But then why are these photos even still being used? Is there any other evidence available? Because this ain't it.

This thread has run its course. I'm leaving it for posterity but we're debating blobs of images now rather than having a robust conversations about American sirens in Australia.
