I have a mint julep cup with a mark that is almost identical to other Meriden Britannia marks that I have seen but it's a little different. The "m" is missing from the top and there are only three interlocking ovals on the bottom. Is this just a variation? If so, does it give indication of the age of the item?
Many thanks for any clarification that can be provided.
