Not the basement of a house, but one of the machine shops on my campus. The machinist let me have this cause he needs to clean up the place and has no use for it. I immediately knew what it was, although I'm not sure exactly what it goes to. It looks and measures to be a 20 mm muzzle brake. It was sitting on the lathe which was purchased from the Navy after the battleship it was on was decomissioned. The machinist said it's been sitting there for at least 15 years.
