Ensko New York Sterling Silver Handled Cup 6"....6.6oz

Robert Ensko started a family business of making modern reproductions of antique silver in New York and he authored a book: Makers of Early American Silver in 1915. Joslin Hall writes:

In this work Ensko was attempting to list known and unknown makers of American silver, their locality and working dates. He lists marks where they are known, and ... concedes the honor of being the first book of marks of American silversmiths to [the] French because Ensko does not actually picture reproductions of the marks themselves, but simply lists them. He also includes several lists of unknown marks, including a group of pieces from the Clearwater Collection, and asks the readers to send him any information they might have. An exceedingly interesting seminal study of American silversmiths.

Anyone who would want to share any info on their experiences with Ensko Sterling would be appreciated........I really couldnt find out much about them except that they wrote a few books on American Silver..Also what does the 500 stand for after the "Sterling Mark" ?
