A couple things to note about this recipe. In 1933, the teaspoonful of syrup has been (perhaps?) increased to a plain spoonful. The 1/4 teaspoon of lemon juice was changed in 1916 to the juice of a 1/4 lemon, and that continues in 1933. The original 3 dashes of Angostura bitters (besides the 2 of orange bitters) were reduced to two dashes of unspecified bitters in 1910 and eliminated thereafter.
My interpretation:
1 teaspoon syrup
juice of 1/4 lemon (= 1 teaspoon)
2 dashes Fee Brothers Orange Bitters
1.5 oz Martini & Rossi Rosso
1.5 oz Plymouth Sloe Gin
Fill mixing-glass 2/3 full of fine ice (beaten with mallet and bag), stir well (20 seconds), strain, serve. — An old and venerable cocktail. One can’t help wishing the Angostura bitters had been left in; the drink is not quite there without them, though still quite drinkable.
