This is West Shore Siren service from michigan right?
Are any of those 612s from sheldon park livonia?
That 812 is rare

Yes we have all 2001's. Plus We are also getting mods i think for the dam failure warning system. There is another discussion on the forum. Many 2001 SRN's, 3 or 4 SRNB's and in the suburb of altoona 2001-130's(2 or 3 i beleive) also we have one decomissioned thuderbolt that I know of. But it has no...

Eau Claire is one of the places getting these and I am guessing they will be modulators because we have a all Federal signal 2001 system right now.
