Meet another gun-shot-grain booster, Sabu:

 

 
   

 

IMDB:

Sabu Dastagir (or Selar Shaik Sabu, depending on your resource) was born on January 27, 1924, in the little town of Mysore, India, which is nestled in the jungles of Karapur. The son of an elephant driver (mahout) in service for the Maharajah of his town, the young stable boy learned responsibility early in life when, at age 9, his father died and Sabu immediately became the ward of the royal elephant stables.

As with many Hollywood success stories, good timing, and dumb luck allowed the impoverished youth a chance for a better life. By sheer chance the timid 12-year-old orphan was discovered by a British location crew while searching for a youth to play the title role (an elephant driver!) in their upcoming feature Elephant Boy (1937). Quite taken aback by his earnest looks, engaging naturalness and adaptability to wild animals and their natural habitat, the studio handed the boy a film career on a sterling silver platter and was placed under exclusive contract by the mogul Alexander Korda himself.

Here's the tidbit that says a lot about the man and the times:

He became an American citizen on January 4, 1944, after which he served in the US Army Air Force during World War II as a tail gunner.
