185. Irving Cocktail

My interpretation:
  1 oz Aviation American Gin
  0.75 oz Dolin Dry Vermouth
  0.25 oz homemade Calisaya bitter liqueur
  1 slice of orange (for shaker), another for garnish

Fill glass (12 oz) with broken ice, frappé/shake 30 seconds, strain into cocktail glass, garnish with orange slice, serve. — This JM 1908 original, a sort of orange-bitter martini riff, first called for Gordon Dry gin and Chappaz vermouth. The instructions invariably call for the orange slice before adding ice or shaking. I added another slice in the shaker for good measure. Straub picks it up in 1913 and also lists the orange slice before the shake.
 

173. Homestead Cocktail

My interpretation:
  1.25 oz Big Gin
  0.75 oz Alessio Vermouth Chinato
  1 orange slice (for shaker)
  
Shake wet and dry ingredients with ice, garnish with fresh half slice of orange. — This Martinez riff recipe seems to appear first in Straub and from thence to JM 1916. It also appears in the Savoy Cocktail Book of 1930, where this interesting note is given:

We may therefore postulate that it has a common source prior to Straub. I add a fresh orange slice garnish to distinguish the drink visually from the traditional Martini, etc., and to indicate that a slice was used in the shaking.

82. Chrisp Cocktail

My interpretation:
  1.5 oz Bombay Sapphire
  1.5 oz Carpano Antica
  1 dash Regan’s Orange Bitters
  1 slice of orange, halved.

Shake with ice, strain, garnish with fresh half-slice of orange; serve. — This cocktail recipe appears first in Straub 1913/1914 and then in JM 1916. It is also presumably found, with two slices of orange, under the variant name “Christ Cocktail” in the Waldorf-Astoria Bar Book (1935), which, though published after the Sad Era, purports to contain the correct recipes commonly used before Prohibition.

67. Cabinet Cocktail

My interpretation:
  1.5 oz Bombay Sapphire
  1.5 oz Dolin Extra Dry 

Shake with ice, strain, and serve. Garnish with half slice of orange. — This recipe in our tradition goes back to Straub 1913/1914, where the garnish is a “slice of orange peel.” JM 1916 duplicates this, but the word peel is omitted from JM 1933. If you follow the last edition, you might end up with something like this:
