As the series began, Clint was driving a wagon around the West, plying his trade as a gunsmith. His big black gelding, Duke, would usually be tied to the back of the wagon, which was pulled by a team of two horses. When Clint found that his help was needed, or he simply found a cause he chose to champion, he'd saddle Duke and ride him until the matter was settled. As the series has progressed, Clint's left the wagon behind and simply began to travel around on Dukeand more recently on his new horse, Eclipse.
Early onin GUNSMITH #4: THE GUNS OF ABILENEClint lost his best friend, Wild Bill Hickok, when Hickok was shot in the back by the coward Jack McCall. He's never forgotten that, and his one fear is of being shot in the same way. That's why whenever someone tries to bushwhack him he becomes incensed.
The Gunsmith is not afraid to take on any manor womanand he'll ride until the day he dies...later rather than sooner, if he has anything to say about it.
