The T-bolt Chrysler replacement on Greenleaf Avenue is a Gridface, as well as the one by Midway. Two gridfaces in Chicago!Stevan Z wrote:So a few nights ago, Logan (Tbolthurricane on Youtube) contacted me stating that through some research, he found a website that showed documents of the old Chicago Civil Defense siren system from 1958! As you could expect I was speechless! The documents even showed the locations and models of Chicago's 99 sirens at the time. According to the list, there were...
5- 180HP Chrysler Bell Sirens (Later replaced with Thunderbolt 1000)
5- 40HP H.O.R. Super Sirex's (All in Downtown)
23- 10HP STL-10
15- 7.5HP Model 7
1- 5HP Model 5
57- 10HP Thunderbolt 1000
14- 2HP Model 2 (All in the loop, were loaned to Chicago for testing purposes)
2- Steam Powered Foster Engineering Sirens (Number as of the early 1950's)
I could not believe it. I take no credit with finding this info, its Logan who found it, I am simply writing this info here with his permission since he doesn't have an account. Anyway last night, we started a map, mapping all of the location. This morning, it was finished and the link is https://www.google.com/maps/d/viewer?hl ... g7jGnE89mE
A few years ago, one of the members found what appears to be a H.O.R. on top of the Field Building in Chicago. With the documents I received, I can confirm it is indeed one and is still standing, and is the only one still standing. Another interesting thing is the documents show that Chicago installed Thunderbolts in Evanston, IL which is a neighboring suburb. We do not have a clue on why they did but can say all of the Thunderbolt's in Evanston were part of the former Chicago system. Again, I'm really amazed at the info I received, and it shows the history of the old Chicago system no one was really 100% sure about. Thank you Logan for finding all of this info!
At the moment, I do not have a link to the documents. When I get them, I will add them here.
All Thunderbolts installed pre- 1960 in Chicago were grid faced, with the exception of 6 installed after.vacuumcleaner wrote:The T-bolt Chrysler replacement on Greenleaf Avenue is a Gridface, as well as the one by Midway.
