I've scoured every venue I know of( books, online) and still can not find this mark anywhere. I feel it may be from Canada as I have many boxes from Canada that are simply marked with "sterling" and a "mark" of some type. If I'm lucky, a name is included but that happens rarely. Having never seen the mark is the reason I bought the box. Any help you can give would be greatly appreciated. Thank you in advance!
