Major Drango has a pistol that he gives to his captain. The gun has ivory handles and a short barrel. Guns if this vintage had walnut handles and 8 inch barrels. The pistol appears historically incorrect.
Drango does surgery on the doctor to remove a bullet near his heart and, after pulling out the bullet, there is no suturing or effort to seal the wound. Drango then goes to the kitchen to wash his hands and there is no blood on his hands before he washes.
Georgia is where the story occurs, however much of the scenery is obviously of the sparse terrain of southern California with its mountain- like hillsides in the background.
