Correction: William Pearce died in 1806, not 1804.
I like the theory, Trev. There isn't a mention in the assay books of a Pearce entering anything in 1821, but rules were a bit lax, and it wasn't unknown for the manufacturer's name to be entered in the book, and the retailer's mark to be stamped on the object.
