Lonesome Dove's CAPTAIN CALL

I'm working my way through McMurty's Lonesome Dove again for the second time since November, and am about halfway through. I started reading it to get a fixed description of Captain Call - whose only physical characteristic, as far as I've found, is that he's "barely middle-sized" - and just kept on going. It's tempting to just draw white-bearded Tommy Lee Jones, but as most any character with facial hair is described as having it, I decided to leave my Call clean-shaven. He's riding his roughly-monikered mare and carrying his Henry. If you haven't read it, or seen the movie, I recommend both.
