I'm hoping someone more knowledgeable than myself might recognize this 'MK'? marking. Judging by the eagle mark and the fact that 'sterling' and '925' are also marked I'm guessing that this was manufactured between 1950-55. I've searched and searched but I can't seem to find the "MK" anywhere. Would anyone happen to know who's handiwork this was? The Thanks in advance, GR
