Tumbledown Ranch in Arizona

This--the 6th in the Range Busters series--is a strange one. The sons of the original Range Busters are taking part in a colligiate rodeo in 1941.

Suddenly, a blow to the head sends one of them back into the past via the 4th dimension where he aids the original Range Busters in thwarting a plan to illegally take over a cattle ranch.
