An early war military design by Indian was based on the Scout 640 (and was often compared to Harley-Davidson's WLA), but was either too expensive or heavy, or a combination of both. Indian's later offering, the 741B was not selected to gain a US Military contract. Indian also made a version based on the Chief, the 344. Approximately 1,000 experimental versions mounting the 750 cc motor sideways and using shaft drive, as on a modern Moto Guzzi, the 841, were also tried.
