Hey all, The marks on this tray are different than the marks on the tea set and I admit it, I have no clue after several hours of trying to find these marks where or when this set was made. Going by the crown I'm guessing Sheffield, maybe, but then I'm lost. I'm not even sure what some of letters are supposed to be, please help! The set belongs to My Mother in law and I'm just trying to date it for her. TIA
