Zapata was the original Che Guevera! Basically a Bolshie.
My my former home town in Arkansas there's a revolver on the wall with a provenance letter tying it to Zapata. IIRC, it's a 7.5" .38-40 Colt New Service.
During the time of Villa and Zapata, you would have to consider most any cartridge, as a little of everything could be found/had in Mexico at that time. The Mexican Government had 7mm Mausers of course, but they also had a good deal of other weapons that many just don't think of. When the revolution started, the flood gates opened and most everything imaginable found its way to Mexico.
While the Mauser was THE rifle of the Mexican government, there were a lot of other guns that were in Government arsenals, including
6.5 Arisaka's
6mm Lee Navy rifles
Colt Potato Diggers
Krag's
Springfields
All of which found their way into the hands of revolutionaries.
Winchester 94's were seized in Winchester marked crates, so obviously US arms makers were doing their part to profit from the revolution. The Winchester 94 was THE rifle of the revolutionaries though. Whether procured directly from Colt, or through intermediaries, tens of thousands of them made their way into the hands of Mexican revolutionaries.
