Analysis of information sources in references of the Wikipedia article "Robert Ensko" in English language version.
A very early study, predating even French's "Walpole List" by two years. Robert Ensko was a New York silver dealer, as was his son Stephen G.C. Ensko, who would eventually publish three more books on American silversmiths and their marks, dubbed "Ensko 1" (1927); Ensko 2 (1937) and Ensko 3" (1948); (an "Ensko 4" was published posthumously several years ago). This book thus precedes "Ensko 1" by some 12 years. 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 only concedes the honor of being the first book of marks of American silversmiths to 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.
