I have recently come in possession of a Silver Ring with 4 hallmarks. From the website, I have found the meaning of two of the marks (London + Sterling 0.925) - However I have not been able to identify the other two marks. The maker's mark is <BS> and the other mark is completely unknown to me. The link below will provide you with four pictures of the ring.




I would love to know how old this silver ring is and who the maker is.
Best Regards, and thank you for your help.
