Congrats on your new siren. I remember the system of RM-130s in Fond du Lac, WI. Very loud sirens despite their small size, and pretty reliable in service. There weren't many changes in production during the ASC years besides the use of a very slow rotator on some of the later batches. Most RM-130s spin at about 3.5 RPM but the ones in Fond du Lac spun at just 2.
