So I was siren hunting for my Washington state map, and I found this in the small town of of Chelan Falls, WA. It is located at 47.8010346, -119.9846141, at the fire station at 24 Chestnut St(apologies for the bad street view): https://www.google.com/maps/@47.8008423 ... 680!8i3840
To me, if I view it from different angles, it looks like a Sterling Little Giant with a single head. The bucket projector, size and motor to projector size ratio all match up. I couldn’t find any pictures of a single head Little Giant anywhere, and a ARS search for the town name showed nothing, so I’m stumped.
