This is the engine room from a Coast Guard buoy tender called the Oak. It was built in 1921.
Buoy tenders are known as the “Black Fleet” within the Coast Guard. Their hulls are painted black to hide the unavoidable scrapes and bumps from hauling buoys and channel markers.
Happy 224th birthday, @USCG!
