Here's another tough one

[The Arapaho Kid]

Who is the actor drawing his gun?

[Russ T Chambers]

Look's like the Duke to me.  And I think the badguy in the background is good ol' Yak.  I almost can place the movie, but it won't quite come out.

Oh well time to get ready to head back to Nevada Territory.  This cold Wisconsin weather is startin' to wear a little thin.

[Texas Lawdog]

The guy with the hat on that is drawing his pistol on the Duke is Denny Moore.  The guy next to him without a hat is of course Yakima Canutt.
