Latest silver purchase is very rare, I believe it to be Wang Hing & Co Circa 1890-1920's. I would love to know what the Monogram on it stands for but I doubt I will ever know. if anyone recognises it I would welcome their feedback
The silver tong's hallmark is pretty clear. The company's name is “和盛", and the silversmith's given name is "蒋". My uneducated guess is that it was made either in Fujian or Guangdong for European clients. A very nice set.
