Thanks for the link I've part way thus far, and skimmed it a bit. It has some good info. Still have not located the date code mark info. I looked around in my books and online in search for chart that will list them. This I would find valuable myself. Personnally I'm going on info I have read about the rarity of silverplate. 90% of what you find is made between the dates of 1880's and 1940's, Pre that date is only small shops and had not caught on in the favor of the middle class, High class still wanted that silver. During the Silverplate age, every middle class wanted to look and feel like a rich person, and silverplate nickle silver items was made by the tons. After 1940's with the advent of stainless and newer less labor intensive metals. Post war bought the housewives easier way of dealing with everyday life. They wanted something they did not have to polish and clean in ways that would not damage the item. Most Silverplate made after 1940's was for the Holiday table, and special parties. Silverplate had a very short life, though it still lives to day, in minor qualities, the hayday of the silverplate was late victorian through the deco years. Thanks for sharing baggins
