Riders of the Range (comic strip)

Riders of the Range, was a series of strip cartoons in the British comic, Eagle.

The heroes of the series, set the American Old West, were straight-talking and straight-shooting Jeff Arnold, and his companion, the older, gruff Luke (surname?). Inseparable partners, the righted wrongs throughout the territory. Once, they very publicly fell out with each other, in order to flush out a gun-for-hire.
