I bought this and the stamp is messed up( stamped over stamp) researching the pattern I found it is Meriden B co. Now looking at the mark I can see enough to feel that is right. It is pattern 25o but I can't find anything much on it. I found pattern 249 which is sterling on replacements.com. I think it is an early 1800's pattern. I tested a worn spot with silver acid and it turned red. Indicating it is sterling. can anyone help me find more on this? I want to verify age, that it is sterling and pattern age. thanks.
