We know brass was a lot more expensive than iron. Part of the problem was temperature control when alloying zinc with copper, so they combined zinc ore with copper as they could not control the temperature well enough to alloy the two metals as elements. We also know that very posh clocks would get solid silver chapter rings. Here we have the other end of the scale, I can't find any record of the maker, not in Bellchambers, Baillies or Loomes. I can't decide if it is Metford ot Melford but can't find anything like it. I also don't know if this is lead as advertised, I think it is probably pewter. They were making plates out of it, this seems a natural step.
