There are numerous single tone 9-port Screamers around my area, and the only visible difference is the housing. Any help on the identifications of these sirens is much appreciated!
Here is the first variation. I am 100% sure that this is a Screamer S-2. It's teeny tiny and takes longer to wind up than the other Screamers.

Second variation. This is the most common variation that's found around here. I originally thought that these were S-5s, but the housing style is that of an S-2, and the motor reads 7.5hp. Your thoughts?

Third variation. Like the first two, this one is 9 port single toned, but the bottom shroud comes down and completely covers the stator like an S-10.

S-2, S-5, S-7.5, or S-10? Tell me what you think!
