This question references 3 ex-pro golfers.

Namely Calvin Peete, Ed Furgol, and Larry Hinson. They shared similar handicaps which actually seemed to help them hit the ball straighter. Furgol and Hinson had withered left arms, Peete's left arm couldn't be properly rotated because of an old break.My question is do you know of any examples that might be analogous in the pool world? And what kind of physical abnormality could result in a more perfect stroke?

The body is designed well to deliver a good stroke. The problems come from our interfering with it. Tight grips, upper arm positioning/movement, and jerky motions to name a few.

To answer your question, perhaps weak muscles that prevent a tight grip or twisting of the wrist.

I believe Jonathan "Hennessee" Pinegar is missing fingers on his grip hand.

I've known quite a few players with missing fingers, and one who had virtually no bridge hand who would shock you with their skill.
Humans have a great ability to adapt.
