Hi, We are looking for help identifying the maker on this Art Deco or Modernist silver box. It has the Hungarian 1937 mark for .800 silver and a makers mark of BK. Any help is appreciated. Thank you in advance, John Z https://i.postimg.cc/BbmySkHg/P1140515.jpg https://i.postimg.cc/GtDQNfzt/P1140517....
