"Flying Tiger Jake" is the character Jake Cutter from Tales of the Gold Monkey 🐒, , a tv 📺 series of 22 episodes that started in September 1982. The mechanic, Corky, and the one eyed dog 🐕, Jack, from Tales of the Gold Monkey, are in the PHP 11 pack
The shirtless male figure in this pack does look a bit like the Doc Savage character as depicted on the covers of interwar pulp magazines. However, I'm not sure whether or not Doc Savage used a gun. I'm going to use that figure for Irving Goff, a hero of the Abraham Lincoln Brigade in the Spanish Civil War.
I would say that Doc Savage, or at least the version depicted on the covers of paperbacks in the 1960's & 1970's, is the "Doc Thompson" figure in PHP 05.
