Hello, I wonder if anyone can help me in identifying this cigar (?) box, and perhaps what it might be worth. It weighs around 1.7 kgs and from what little I’ve learned about the hallmarks on this website, was assayed in London and is sterling silver. It refers to the Guild of the Nineteen Lubricators, which from what I can tell is a registered charity in the UK. If anyone has any information on it, that would be very helpful!
