Many other model engineers have contributed numerous designs notable for their enduring popularity. Prior to the appearance of Engineering in Miniature magazine in 1979 and Model Engineers' Workshop in 1990, these authors wrote almost exclusively in Model Engineer. Among these, Edgar T. Westbury produced many internal combustion engine designs, W.J. Hughes designed many agricultural and traction engine models. Colonel C. E. Bowden will be remembered as one of the most prolific experimenters with model aircraft, model boats and radio control, particularly his successes in powered model flight co-operating with E. T. Westbury, who made the Atom Minor engine that powered several of his early models. Martin Evans produced a great many more model locomotive designs, George H. Thomas specialised in designs for workshop accessories, Tubal Cain (T. D. Walshaw) developed a number of stationary engine designs, and Claude B. Reeve produced many clock designs. Ian Bradley and Norman Hallows wrote individually and together under the pen-name of Duplex on a wide range of topics, notably finely finished and ingenious tooling. Don Young contributed locomotive designs to Model Engineer and then published his own quarterly live steam magazine Locomotives Large and Small from 1979 until his death in 1994. More recently, Kozo Hiraoka has authored several series of logging locomotive articles in the U.S. magazine Live Steam. Among living model engineers Cherry Hill is notable for her small-scale working models of unusual early steam vehicles.
