Henry Greenly on the back of the "Challenger" spirit-fired locomotive, 1924 Model Engineer Exhibition, Royal Horticultural Hall. Greenly and LBSC had been challenged to compare examples of the two types, in public. W.J. Bassett-Lowke, with only his head visible on the right of the photo, appears to be enjoying the proceedings more than Greenly. From http://www.brightontoymuseum.co.uk/info/Category:Henry_Greenly
