Mystery Fire Truck Siren

[Fanman]

I found this in some fire truck pictures (Credit to Abdul Saboor Khan)

It looks like a Federal Model 76 but I might be wrong. Any ideas?

That siren appears to be a Federal Signal Model 77L. A quite rare siren. But the fins on the side look more like the ones from a Model 78. The siren could have been a little modded at some point due to those different fins. The Model 78 is shaped a little differently than a 77L.



Here is a Model 78:
