My Nana passed away last year in her 90's (I live in New Zealand) and I have been given this beautiful thing. From my research it looks to be a biscuit barrel. It has EPNS stamped on the lid. Under the lid is a bee stamp with 'L' and 'B' in each wing (see photo). I think it's electroplated silver, going by this website (which doesn't give a name of the maker):
http://www.silvercollection.it/electroplatesilverUNI.HTMLIt has the numbers/ letters 'R413701' scratched in to the glass at the bottom of the barrel on the inside. My Mum thinks it may be depression glass - I'm not so sure.
I was really hoping for a name from who made this and what year approx - and if I'm right that it's a biscuit barrel. Thanks!
