In the "Savoy" Harry Craddock says this drink is "Well-known and very popular in the American Bar of the S.S. Europa."

This is one of those rare cocktails which doesn't feature one of the six base spirits (brandy, gin, rum, tequila, vodka, whiskey). Benedictine carries the day here, and since it is 80 proof like a base spirit I suppose it's just a slight deviation.
