I've been researching silver marks for the last two hours and can't find much about these! What's confusing me is that they're not in the order that they are when I found these marks online, and the word "sheffield" stamped into the pot isn't found anywhere apparently! Could someone PLEASE help me identify this item (The only thing I can figure is that it was made in Sheffield). Is it sterling silver? Is it old? (This is either a tea or coffee pot, btw.) Thanks in advance!!
