Machinist - Welcome to the gun show 1917 Jigsaw Puzzle

Colorized photo from 1917 Original Title: Navy Yard Torpedo Shop Location: Washington DC This is the Navy Yard shop in Washington DC, built in 1799 (though this structure was probably built later). Over the years they have built all kinds of things. Special cannons, torpedo's, steam ships, and so on. During World War I they are built torpedo launchers (which is what we see here). A torpedo launcher is a tube that holds a torpedo, mounted to a battleship, but it works just like a normal torpedo once it hits the water. This factory makes both things, but this room just does the tubes. By World War II, this location was the largest ordinance plant in the world. By 1960 they had 188 buildings, across 126 acres. For the most part, just the guns and torpedo's were made here. But by 1961 they closed this place down, and by 1964 they turned most of the buildings into office space. Bonus: Can you find these items? A single shoe on a shelf A guy wearing a fez (hint his back is turned to us) There is a tomato can high up. There is also a large saw blade.
