Hmmm...not sure where your link to the book is. I did, however, find the 2014 revision of the Savoy Cocktail Book online at openlibrary.org. It reproduces the original artwork by Gilbert Rumbold from the 1930 edition, but the recipes have been expanded and differ somewhat from the 1930 Martino Publishing reproduction I have. The historical forward to the 2014 edition is very helpful for sorting out the messy history of this book. As for my copy, there is no indication in the material at the front of my reproduced edition that it is any kind of revision or update of an earlier edition. The Scoff-Law is the last cocktail on p. 143 in my version, followed on p. 144 by Scotch Mist and Scotch On-the-Rocks above a Rumbold drawing of a Spanish dancer and guitarist, then (on p. 145) is the Screwdriver, immediately followed by the Seventh Heaven #1 and #2; no Self-Starter or Sensation. For comparison, in the 2014 revised edition, p. 143 has the same 4 recipes as my edition, ending with the Scoff-Law; the text is slightly edited and re-typeset. On p. 144, the Scotch Mist and Scotch On-the-Rocks above the dancer and guitarist have been replaced by the Self-Starter and the Sensation, indicating significant re-typesetting of the document, i.e., a revised edition containing new recipes contributed by unidentified staff from the Savoy Hotel. There is no Screwdriver in the 2014 edition. On p. 145 of the 2014 edition is the September Morn (not found in my edition), the Seventh Heavens, etc. My best guess: Santa gave me a photo-reproduction of the original 1930 Craddock edition, while the "1930 edition" you are using is actually a later, revised edition that may have reproduced the artwork and the original 1930 title page, as in the 2014 edition, but with a somewhat revised selection of recipes. For instance, my version contains the Scotch Mist and Scotch On-the-Rocks recipes, which consist of scotch poured over, respectively, shaved ice or cubed ice and garnished with a lemon twist. These look like prime candidates for removal and replacement by actual recipes a bartender might mix, suggesting that my edition is an early one. Take a look at the historical forward in the 2014 edition and see what you think. Slainte!
