IS stands for the International Silver Co. and unless it says sterling or 925/1000 it is silver plate.
The markings "E" and "P" on silver flatware typically indicate the manufacturer or the pattern name, while "800" signifies the silver content. Specifically, "800" denotes that the piece is made of 80% silver and 20% other metals, which is a common standard for silverware, especially in European countries. This level of silver content is lower than that of sterling silver, which is composed of 92.5% silver.
Wm Rogers 840 refers to a line of silver-plated flatware produced by the Wm. Rogers company, known for its high-quality silverware. The "840" typically indicates the silver content, suggesting it is made with a high-quality silver plating process. Wm Rogers is a well-respected name in the flatware industry, and pieces marked with this designation are often sought after by collectors.
"Chippendale" is the name of the pattern. You can think of it as a collection; "the Chippendale collection." The manufacturer (in this case International Silver Co.) would make a whole line of flatware, hollowware and serving pieces with the same matching pattern.
To identify a silver flatware maker, look for hallmarks or stamps on the pieces, usually found on the underside of handles. These markings can include the manufacturer's name, a symbol, or a date code. Researching these hallmarks through reference books or online databases can help pinpoint the maker. Additionally, knowing the style and design of the flatware can provide clues about its origin and era.
Oneida sterling flatware had a mark with a "cube" on the left side of the name. According to my reference, it is "The silver cube. Our silversmiths' mark of excellence," and was used since 1965. The cube is apparently a mark of excellence. (American Sterling Silver Flatware, by Maryanne Dolan.)
