as you can see from the first image the stone or whatever was there has fallen off and i was unable to find it.

the second image shows the different marks, the initials appear to be B & W or B E W.

i haven't a clue as to what the hallmark might be other than maybe a key.
metal detecting is simply my favorite hobby, i love digging up things from the past or items of interest especially if i can get a bit of history for it. so any info on this item or a direction to point me in would be greatly appreciated. thank you again
kind regards
