Silver or fake?

[Bartholomew]

Sheffield marks

Hi/ can anyone verify these hallmarks as Sheffield 1918/19 please. A slight dispute with some American cousins who say these are faux silver and are plated marks. As far as I can see they are correct although the maker is unlisted. These are the only images I have so far. [image] [image] [image]
