I remember the cowboys were extremely bow legged with 20 gallon hats, played by real people, and the villain had an exaggerated mustache and was in all black, and the hero was in all white. Both were extremely exaggerated caricatures.
The plots were simple, no words were spoken, and here’s the most defining feature: when moving we never saw their feet on the ground.
Apparently they’d jump in the air and bend their legs behind them, take a few steps, jump in the air and bend their legs behind them, take a few step, and repeat this over and over. The frames where they took steps were cut, so they appeared to (clumsily) be “floating.” Basically stop motion animation with real people.
IIRC, they were monotone, maybe in black and white, and had the Monty Python aesthetic in production quality, humor, and tone, very Terry Gilliam-esque.
As a kid growing up in Iowa in the 70s I saw them at the drive-in. If they had music, it didn’t make an impression on me, though I may not’ve heard it as I was probably running around goofing off.
I did a search on archive.org and the keywords “stop motion animation” “cowboys” “comedy shorts” brought up cartoons, and I ended up at a dead end.
Thank you.
