Oh boy do I have some nice contributions to make! Here we go!
1. Fedelcode Model 5 and Federal 508-128, Lisbon, ND. The 508 (along with another one and a T-121 in town) are only tested on ND SWA, and the 5 used to do a noon & 6 PM blast until a city noise ordinance killed that joy...
2. W.S. Darley Model 2 and Federal Model AX (yes you read that right...) in Christine, ND. Both appear to be abandoned with wires cut, but a local was adamant that they work...
3. Federal Eclipse-8 and Federal Model D in Fingal, ND. I'm guessing the D is a street clearing siren...in a small town...
4. Federal Eclipse-8 and W.S. Darley 3V8 in Gackle, ND. E-8 is a noon and 6 PM blaster.
5. Now for my personal favorite! An Erick Model 445, Darley Champion horizontal, and a Federal Eclipse-8 in Fredonia ND.
