Hi Foxy;
The article I read was written by Frank Jardim. Mr Jardfim served as Director of the Patton Museum at Fort Knox KY from2000 to 2007 & apparently did a good deal of research on Patton while in this capacity. The Ivory handled Colt is on display there. He did mention that the three dead Mexicans were strapped across the hoods of the cars like game & carried back to camp which highly impressed Pershing. It would seem though that on this particular mission the Americans had no horses with them, only the three cars which were stated to be Dodge Touring cars, no mention of a Model T Ford on this day.

Patton had broken Cardenas' arm with his shot. A bit later Cardenas feigned surrender but when he got close to a soldier he raised his pistol to ambush him & the soldier shot him dead with his rifle. It was said that Patton claimed a lot of souvenirs, including Cardenas' sword, pistol, saddle, lariat & spurs.
While Patton may not have actually killed any of the three Villistas he did, in fact, play a major role in their deaths & shot that old Colt hogleg quite effectively.
