1914 In the October of that year, James Howarth, who had once worked for Bradbury and Co, offered his new range. At the bottom was a model fitted with a 269cc Villiers two-stroke engine and direct-belt transmission. There was also a machine fitted with a 2.75hp, 349cc four-stroke Villiers engine, two-speed gear and chain-cum-belt drive. Larger models were also listed using 6hp or 8hp JAP, or 6hp MAG engines, the MAG with a three-speed gearbox. A racing model was added in the November, fitted with a 3.5hp MAG engine.

1915 JH offered the two Villiers-powered machines, plus models using 3.5hp and 6hp MAG V-twin engines, the latter with a three-speed or four-speed gearbox.

1916 The engines used for that year were the 269cc Villiers, a 3.5hp JAP and V-twins of 3.5hp, 6hp or 8hp from MAG, or 6hp or 8hp from JAP
