A Victorian cut glass mustard pot with domed silver lid and collar, fully hallmarked for Sheffield 1857.
I have included a large, early, matched mustard spoon (10cms, 7g.). Hallmarks to the spoon consist of makers mark (twice) only. Very likely Georgian and undoubtedly silver, nontheless I have tested it and it tests as silver. Please see final photo for silver test result. A piece of HM silver is photographed alongside for comparison purposes only (not included).
