I recently bought a house and today was tearing out some cabinets in the garage. Then I found this cylinder. It's rusting steel, a legit 75+ lbs, and seems dense inside. The weight does not quite feel evenly distributed across the length. Length is approximately 36 inches with a diameter of 3-4 inches. Also the cylinder necks in a little bit under at least one of the metal straps and maybe both. I cannot find any markings at all on the cylinder.
Does the cylinder look familiar to anyone? What do I do with it? RPG cartridge comes to mind, but it seems far too heavy for that. Wiki says 10-15 lbs even for larger ones. Same general weights for mortar rounds too. Really hoping it's something more benign.
