I’m trying to date and identify the hallmark on this silver lid attached to a brown stoneware jug. The jug was made around the turn of the 18th century (1780 - 1820) the lid was likely added later than at the time of manufacture. I have been told the mark may be German - but I doubt that given that the jug is English and the inscription on the lid is in English. Any help would be greatly appreciated.
Following a suggestion I am attaching some additional pictures - hope this helps
