The list of 57 stars on the inside front cover of the American Nautical Almanac for the year 1953 (Washington, 1951) is indeed the same as nowadays. 8 items have footnotes indicating name or spelling changes: Atria (formerly Alpha Tri. Aust) Avior (formerly Epsilon Argus) Diphda (formerly Deneb Kaitos) Eltanin (formerly Etamin) Gacrux (formerly Gamma Crucis) Menkent (formerly Theta Centauri) Mirfak (formerly Marfak) Suhail (formerly Al Suhail) From the preface: "This volume of the American Nautical Almanac was prepared under the immediate supervision of G.M. Clemence and Glen H. Draper. The nature and the arrangement of the material are the same as in the volume for 1952, with the following exceptions. The names of the stars have been added to the list (now in alphabetical order) on the daily pages, and the time of meridian transit is omitted. In order to eliminate variations of usage, the list of 57 stars has been revised, and a few of the names have been altered, as noted on the inside front cover." This answers your question as far as the date and authorship of the final version of the list of 57 navigational stars is concerned. Sorry for not checking earlier. I never guessed that the only volume of an old post-war almanac that I have sitting around would be relevant to your question. Herbert Prinz
