This recipe is a broad interpretation of Jacob A. Didier's 1909 original and the Casino recipes that follow in Hugo R. Ensslin's 1916 book and other subsequent...
Interesting range of comments with respect to Difford's vs "original" version which if I interpret comments correctly, differ over primarily how much Maraschino / sweetness one prefers in this drink. I always start with the Difford's recipe and did so in this instance notwithstanding usually avoiding cocktails with orange juice. To my surprise, presumably because of the lemon, I found this to be a lovely and well balanced cocktail. Not too sweet, and for me more importantly, not too orange forward. I will compare to the "original" recipe at some point.
