She’s Oil Mine

Buster Keaton romantically pursues an heiress with oil wells. Two mechanics do a lot of slapstick comedy, and accidentally seal heiress in large tube. Heiress falls in love with a mechanic, so Buster Keaton decides he needs to fight this man in a duel. It’s a big production with men driving up in beautiful cars/ automobiles wearing top hats and canes. The pistol duel skit has a running gag where one of the duelers continually tries to cheat.
