Kilduffs & Cheryl — I believe I have found proof that the letters framed in a shield on Mappin & Webb's
Prince's Plate,
Queen's Plate, and
Mappin Plate are date letters.
I can't post the information here, as the main element of my proof is evidence from a set of spoons offered for sale on a commercial website, so please link to the topic on the Glass Message Board.

What is your impression of George Mappin's deafening silence on these date letters?
