My interpretation:
1 oz Dubonnet (or Saint-Raphaël) aperitif
0.75 oz Martini & Rossi Extra Dry
0.25 oz Plymouth Gin
Fill mixing-glass with broken ice, stir, strain into cocktail glass, serve. — This Dubonnet treatment of the Saint-Raphaël aperitif resembles the Dubonnet cocktail proper. It first appears with the angelic elixir in JM 1910, substituting Dubonnet in 1916; the rest of the recipe remaining unchanged through 1933. A Raphael Cocktail does not appear in the usual cocktail books of the period; it may have come directly from the producer.
