Hi,This lid appears to be the most common English Pot Lid found in the U S and is also very common in the U K. It would date to around 1905 as it has the Kings Crown in the trade mark which dates it post 1901 when Queen Victoria diedhttp://www.ebay.co.uk/itm/Vintage-Vi...item35e65aaeda Hopes this helpsDavid
Hello; Lid is pre-1891, after that, country of origin would have to be marked, in this case, ''England''. One of the most common potlids, found throughout the English- speaking world, quite common in Canada, where ANY lids are hard to find. Still nice find, though, have dug a few marked with & without " England'' in Ottawa, Canada , from c 1910 dumps. Dave
Good luck with your search and hope you are looking in a privy as will be much easier to find both pieces as I have found that usually if you dig in a dump the chances tend to be for maybe 2 lids complete with bases for every 50 lids or 100 bases.
