I have a set of 12 silver fish knives and (sadly) 11 fish forks, definitely not plate, with bone handles. The assay marks are very small and the cutlery was much used (I should know, they were my mother’s!) and I wonder if anyone can decipher the marks? WH in an oval suggests the Birmingham maker WM Hayes, but I’ve seen that the criss-cross mark to the left can mean Sheffield…? Help!
I agree: electroplated. The lettering reads WH&S EP which is correctly identified by the previous poster as William Hutton & Sons, electroplate. The crossed arrows mark is their trademark.
