Thanks to Italo-West-Fan I could watch this oddity.
Set in Guaynas (is that Guyana?) instead of Mexico and in the early 60s (judging from clothing, music, cars etc.) this is not a spaghetti western, but it could almost pass as one. Nearly all ingredients of a good Zapata are there, including Eduardo Fajardo as a local dictator and Fernando Sancho as a hard-drinking, ebullient revolutionary leader. The plot is quite complicated and nobody is what (and who) he pretends to be.
The protagonist is a sound-engeneer who uses his skills to confuse his opponents. We also get trains, automobiles, helicopters and God knows what more (yes: beautiful women)
Cheaply made, shot near the Costa del Sol, no sign of authenticity whatsoever, but remarkably enjoyable
I write a short review this week and will also change the Film's Page
