The Siren Board

Slight bump but super... Is that A2 a 5 or 4M blower? Do you know? If it was 60s I assume 5M? The one on the roof of the grain elevator a 6M?

I don't know about the old St. Peter siren's blower. The type Federal used during the 1960s would have been it, unless they swapped parts at some point.

The 1000T on the now-demolished grain elevator would have had an older "pig iron" blower. They tend to make a rather distinctive chugging noise compared to the constant whir of later blowers. I don't have all the blowers categorized although I'm welcome to overview the Thunderbolt blower's timeline since I'm studying these sirens as well.

Sorry for the bump, but do we know if the ripon thunderbolt is active?

Not sure Caleb. I don't get out their often, the last time I was there it looked to be in a different position than the last time I went by

I believe ECS () put a new radio on it this summer and it should be working again.

Smallish bump, but there used to be a tbolt on 114 S Main St #276 in Fond Du Lac
No idea where it went but heres a photo

Well. I thought there was one there, but did not see any images or evidence until now. +1 Karma for you!

Wow! There it is, the "combination building" Thunderbolt. Prior to this, all we had was the black and white newspaper clipping from when it was installed.

Just speculation, but I wonder if this one was moved to the city/county building in the late 70s when that was built. After that, I'm pretty sure this one then moved to Malone, WI on the Co-op. It was a 5/6 port on tap 7 when it was there. Really high pitched.

I might be able to look to see if it was moved- most likely was. I can try to find other photos aswell

I looked for a while and I think that's the only photo showing one of their bolts. Photo date is from 1966-1971
