A 1940s era Sterling Siren Model “F” factory siren. This siren spent decades outside of a Long Island, NY firehouse, acting as a street clearing siren to allow fire engines to exit the station unimpeded during an emergency. It was decommissioned a few years ago and popped up on eBay, and I was able to get ahold of it for cheap as the seller didn’t know its worth. Model F sirens are very hard to find, as they haven’t been made since the 1960s, and the need for street clearing sirens has lessened. I believe there are less than a dozen left in service across North America.

Mine is in very good running shape, despite its age. I lubricated the bearings recently (brass sleeve bearings) and let the motor break in. It isn’t quite as loud as my Federal Sign & Signal Model “L” (built in the 1960s) but still packs a punch. I usually set them off with the city sirens every Monday. It does need cosmetic restoration, as the paint is badly weathered and the projector has some dents in it, but it won’t be hard to fix up.
