It might be company dependent or a 1975 model released in 1974. The 1974 Norton Commando MK II released in the states had a right hand shift and left hand break. It was the last with that setup. The first left hand shift Commando was released in the states in 1975. Based on
Mr. Chadwick's page a few right-hand Triumph models could still be obtained from the factory in 1975.
