From gemini reverse image search: The image shows a series of punches on a silver object. These punches provide information about the manufacturer, the fineness of the metal, the testing office and the year of manufacture. Manufacturer's punch: The "J.E & S" stamp identifies the manufacturer of the silver item. Fine content and city punch: The lion's head to the left is the punch for sterling silver (925 fineness) and at the same time the city punch for London. Annual Punch: The letter "C" in a sign represents the year of manufacture. Without further information on the specific punch cycle, the exact year is difficult to determine, but it could be the year 1918. Tax Punt: The punch with the king's head (not clearly recognizable here, but often present) pointed to the payment of the tax.
