I have a antique silver vase that is 4 1/4 inches high.There us engraving of a lions head with flames coming out of mouth.The bottom hallmarks are as follows:
ok well the crossed keys puzzles me. Henry wilkinson & co Used the crossed keys as a trademark, they were sheffield plate before being granted a license to use electroplate before then going bankrupt and walker & hall taking over! But the ‘lions head’ looks like the assay mark for london pre 1821… The dates of the keys and the assay mark do not add up though… Puzzling.
