I found this topic similar to mine so I am writing here. Dear experts, please help me understand the originator of this tankard cup and the possible date of manufacture. As far as I know, its made from metal electro-plated with nickel silver. It has 'EPNS' and 'S' for Sheffield (perhaps) and 'A' or 'LM' or 'AM' in one sign marks on the base. Thank you in advance!
