I am looking for some help identifying the enclosed Hall/Trademark, it is off an Art Deco/Nouveau (Silver or Silverplated) Tea & Coffee Set could be from France/Paris. Not been able to find anything about the marks but think they read " Lutetia & G W" plus "12 GRs" - any help is greatly appreciated.
Thanks Thomas
