There is no sign of the wagon and horses when Chip's father is killed, but he rides away on a saddle horse with Land ry and also with Tim at the end of the movie.
After Landry shoots Dobbs from the window, Chip fires a shotgun at the window. But there's no damage to the window, and the curtains don't even move, as would happen if they were hit by buckshot from the shotgun. This shows that the gun fired blanks.
When Landry is in the bank and closes the window shades on the door they do not close all the way. When he goes back to the door to open it for Chip the shades are pulled all the way down.
