Old East Lansing, MI & Meridian Twp. siren system

[Greenrid]

Apparently East Lansing and Meridian Twp. had Thunderbolts at one point (Meridian also surprisingly had a 20v2T!), but they were removed and replaced. I know where most of the Meridian Thunderbolts are, being replaced around 2013, but I don't know where the East Lansing Thunderbolts were. If you go into street view to the oldest one, you don't see any, so they must have been replaced before that.

Does anyone know where all of the Thunderbolts and other sirens were in East Lansing & Meridian Twp, and what was the year they were replaced?

Where'd you find evidence of a 20V2T? The only one I know of out that was replaced a Thunderbolt, and was in Bath Township. It has since been '130d.

That's the one I was talking about! I accidentally forgot that it was in Bath twp, not Meridian twp.
