This isn't close to any of the various spec from the original sources. The rum ratios and styles are off, pink grapefruit wasn't used and the punch version, closest to what is listed here, doesn't have pineapple and has cinnamon syrup. Sippin' Safari has all 3 cannon recipes and the story around them.
The Trader Vic (pseudo) ratios (2+:1:1/2:1/8:splash) make a better drink and show case that fine interplay of the lemon and rums in a not quite a pineapple/lemon daiquiri way. The orgeat and grenadine need tuned downward, starting with 1/4 or less, to find that balance and avoid "fruitloops punch" gulf. A punchy float can work nice as well, WP109/S&C/RumFire or Demerara, to bring it up out of the sweet.
