As a siren enthusiast, I love when towns still carry on the traditional noon siren blasts. That doesn’t happen much here in Ontario anymore.
FYI, Milo’s siren isn’t an air raid siren, small sirens like Milo’s (a Federal Model 2 in this case) are typically fire sirens used to summon volunteer firefighters to the station during a fire call. Milo’s is on the fire department, so it’s probably the fire siren. They’re usually tested daily or weekly to make sure they work when needed.
A lot of people just call every siren an “air raid siren” even though no siren has been built for that purpose in 40 years in North America lol. It’s entirely possible they had an actual air raid siren at one point, probably built by Canadian Line Materials.
