Extremely Rare Sirens

[Tyler]

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.)

No i'm talking about the Thunderbolts (7) that Federal made that had a round horn. It didn't make it because for some reason those thunderbolts froze up in the winter and wouldn't function except for the ones that were always in mild conditions they worked just fine. Another reason is because it was harder for Federal to make fiberglass horns if i'm not mistaking.

Sources? It was proved some time ago (if I recall, in an interview Jason did with Earl Gosswiller before his passing) such a thing never existed. Granted, I think that was on the old old board and I could be confused since it was so long ago.

nope. back when the Thunderbolt was designed, they didn't have CAD or Photoshop or any of that. All of the engineering drawings and specs were done by hand with pencil, a set of triangles, a slide rule, on a drafting table. The advertising copy was done by hand by artists who were told what to draw. It's why the earliest Thunderbolt ads had rounded rotator and blower boxes, and why some early catalogs show 2T22s with the wrong number of horns. There was never going to be a Thunderbolt with rounded boxes, or a 7/10 port 2T22. The artists drew a general concept of what the thing was going to look like.

you're very mistaken. Historically Federal hasn't used fiberglass very much, if at all. ACA uses fiberglass extensively, and they only made very few Hurricanes with square horns before transitioning to the round horn. Fiberglass is a pain in the arse to work around sharp corners; but much easier to lay flat around gentle curves.

It was just a prototype from what I heard. I can't remember where the info came from off the top of my head but i'm sure someone can help me with this.

Until we hear otherwise it's just a myth.

I thought there was a thread on here in which someone found a round Thunderbolt panel at a former nuclear test site and contacted Federal about it? I remember someone telling me about it, I do recall that it was an old thread.

I also recall that, and I also seem to recall it being from Franz. He spewed more bull than our current president does.
