[trish bailey]

It is difficult to read some of the letters between the patent number and the symbols. I will tell you what I do see.
Patent number 21167637 pictures of an anchor walking lion and a capital B with a circle around it. Any information would be appreciated.I have pictures but did not know how to post them. Thanks

British Sterling - English Hallmarks, Irish Hallmarks & Scottish Hallmarks

Those are definitely British hall marks. The rampant lion means sterling, the anchor is a code for the city it was assayed in and the B is the date code. If you go to your library or search the net you can find out the date and place of assay.
