In 1971, Francis L. Cappaert of Birmingham, Alabama, bought Diamond-Reo from White. And, at about the same time the Diamond Reo C-116 series was introduced, which featured Cummins NTC-335, NTC-350, NTA-370 and Detroit Diesel 12V-71N engines. Despite new model introductions and excellent reputation Diamond Reo was forced into bankruptcy on December 6, 1974.
