They are both ACA Screamer sirens.

The physical size of the siren is respective to the horsepower it has. Screamers came in 2, 7.5, and 10 horsepower models.

Nice photos, I'm temped to look at the high-resolution versions.

Awesome finds! I would say that's technically the first 7V8-B (note the large brown box at the bottom of the pole). Also, with the P-10 you have, that's technically an RM-127 because it was made after ACA switched to ASC.

Thanks. I honestly can't tell the difference visually between the 3V8-H and 7V8-B, is there one? Waldenburg is a very small town and I imagine that siren covers it entirely. There's also a 7V8-B in Wiener, AR with the exact same set-up as Waldenburg's. I also saw Whelen Hornet's in Newport, AR and Amagon, AR but was unable to get photos of them.

For those interested, here's the manual for Sentry's 16V1T-B/7V8-B:

Not sure if I was allowed to share it, so my apologies to the mystery provider should he happen to be reading this.
