What year was Noritake china Somerset 5317 made?

Answer 1

From what I have gathered in speaking with a Noritake historian, the first two digits are the last two of the production year. The last two on the stamp are the place the pattern sits in the line of patterns created in that year. In your case, your pattern was the 17th pattern produced in 1953. . In my case, my backstamp reads 3606. She told me it was the 6th pattern produced in 1936
