Absolutely no clue on this one. One side has the remains of a lead seal. Any ideas?

Yep

Early 19th? Are you sure? Because the dump was mostly early 20th.

Seems like odd bracketry just to swing under a clock. I'm guessing it was some sort of lid for some sort of tank or kettle that could lift (leak) to prevent pressure build-up.
