Unlike the contemporary Pegu Club, this is structured as a cocktail, in the original sense, rather than a sour/daisy (fancily sweetened sour). Basically this means less juice. Willett provides alternative ratios of gin to orange liqueur: 3:1 (credited to McElhone, 1922) and 1:1. This ratio is credited to Craddock, 1930 (the Savoy). Willett calls for less lime juice (though not much less) than older sources.
