Loft find. So don't know really know anything about them.
Pint Pewter Tankard - mark on the side - think it is E.R with a crown - 360 - LCC
Gill Pewter Tankard - mark on the side as above
Believe the LCC stands for London County Council
E.R - Elizabeth Regina and 360 is the mark adopted from 1891-1965 but now goes to a district in London but I don't know which one.
Comes as seen. Collection Downham BR1
