Most pre-war low tone sirens in Germany had three ports, but there may have been some smaller, high-speed sirens with only two ports. A one-port siren would require a ridiculous motor speed to make any meaningful noise.

I would presume they're Danish, like most things in Greenland. The whole population is 50,000, so I doubt they have a siren factory.

Nice. It reminds me of the day my ship arrived in Piraeus (Athens) early in the morning and docked next to a naval complex. I awoke to the sound of bugle calls and the Greek national anthem.

There was a video of one of Massapequa's sirens many years ago but it disappeared.

YouTube kids and their incessant Roblox videos have better sound quality than this thing.
