Mystery Omni-Directional Siren my Uncle collected

That is most likely a repainted Mach 5. I know because the top shroud is missing and there is NO line to know that it's had a shroud there.

I don't think mach 5's had 4 or 3 shrouds. also there is no extra area on the bottom on this siren (nothing below the bottom shroud).

Multiple other people think it's a Mach 5, and I know it was most definitely

That doesn't seem entirely correct, mainly since the bottom of the Actual 5 is clearly visible beneath the bottom skirt, BUT on the Mystery Siren, it's housing ends where the bottom of the bottom skirt ends. If it IS a 5, then it's been heavily cut down and given a steeper bottom skirt.

Yeah but it might be an early Mach 5

It's a Model/Mach 7

Well it's certainly not a 5.

I'm pretty sure it's a Mach 5, knowing the dual headed Fedelcodes only came in 3 hp, 5 and 10. Also, I think there's a 50% chance there's enough space for two shrouds, since the siren has a similar build to Glandorf's Fedelcode. I ain't no expert, but it doesn't sound too far fetched. Someone said in this post it was in storage for a while before being taken out and sold on ebay.
One thing to point out is if this is a later dual headed model? Given rotor pictures were posted a while back, showing straight vanes in the design.
