Wilson Atomatoys Factory

There's a named Super Mutant in the second floor (Big Mack). In the same floor, there's a steamer trunk and the Wilson Automatoys Factory ID on the table nearby. This is used in the security door in the lower ground that gives you access to more... junk.

The super mutant light body armor found on the stairs at the rooftop can’t be equipped by humans. This is for your super mutant companion, Strong to use. (Much like dog armors that Dogmeat can exclusively use). There area a lot of Giddyup Buttercup parts on the assembly line in the lower floor. There's also a weapons workbench in the same floor.

Outside, there's a generator where you can eject a Fusion Core.

On the rooftop, there's a ramp you can use to walk on the large pipe. Enter the hole through the pipe to find a red trunk with some good loot inside.
