I have a travel set in vermeil, 22 pieces in mahogany case, purchased 35 years ago in Belgium. I was led to believe at the time that it was French. I have studied the hallmarks and suppose it to be French 1819-1838 but I cannot find the maker whose initials appear to be P. NB Above the P.NB within a diamond are what appear to be 3 ducks? Any help appreciated with maker or possible dates.
