This oil cup was discovered in 2001 in a mass of concretion withother various tools. These tools are most likely the spilled contents of a tool box and included different sized hammer heads, a small oil can, a lead ingot, and glass from a lantern. The mass was concreted to a large copper alloy pipe.
This is a nice shot by Jason from photography of the three recently conserved Dahlgren gun tools: a sponge on the left, a Robinson worm in the middle, and a shot ladle on the right. Handling the objects during the photo session reminded us of how fit the gunners had to be to do their work. The ladle weighs 22 pounds empty and without the handle. The sponge head is 15 pounds. Ouch.
