​The Presentation Inscription (Front)
​"Presented to Royce J. Clint on the occasion of the 25th Anniversary of The Robertson Group plc, 1987"
​While the tray was manufactured decades earlier, it was kept or acquired as vintage stock to be engraved and presented as a corporate long-service or anniversary gift in 1987.
​The Maker's Stamps (Back)
​EP: Stands for Electroplate. This indicates a layer of pure silver has been chemically bonded to a base metal (like nickel or copper).
​J D & S: The initials for James Deakin & Sons.
​The Symbols: These are pseudo-hallmarks (the letters J, D, &, S in individual shields) designed to mimic sterling silver hallmarks, which was common practice for electroplate makers to look premium.
​The Desk Lamp Symbol: At the far right is a tiny stamp of a table/desk lamp, which was the official corporate trade mark of James Deakin & Sons.
​Y3333: The manufacturer's internal pattern/catalog number.
​12: Stamped on the front rim, indicating a standard 12-inch diameter.
