Monogram's popular Range Busters series, an obvious imitation of Republic's Three Mesquiteers, spawned 24 films between 1940 and 1943. Ray "Crash" Corrigan and Max "Alibi" Terhune were both ex-Mesquiteers. John "Dusty" King, once a big-band singer with the Ben Bernie Orchestra, rounded out the trio. Corrigan and King were replaced in other installments by different actors, while Terhune was the only member to appear in all entries.
Trail of the Silver Spurs (B&W, 1941): The Range Busters are on the case when gold disappears from the Denver mint. The steadfast trio masquerade as prospectors and get more than they bargained for when they find themselves in a cobwebbed ghost town where ominous sleepwalkers haunt the town and gunmen stalk the shadows.
Tonto Basin Outlaws (B&W, 1941): A violent band of outlaws are cutting a swath through Wyoming, robbing stagecoaches and rustling cattle, but their criminal days are numbered when the Range Busters are assigned to bring them in. Crash Corrigan infiltrates the gang and must find a way out of trouble when his true identity is discovered.
