Let's just take the first two from the left. The Road Roller is a 1935 Aveling DX, based on a design by E. T. Westbury at a scale of 1 1/3" to the foot. The second item is a Dividing Head, a "Double Worm Reduction & Integral tailstock." Neat Huh? I'll cover the 2 center models in the next picture. Over to the far right is Alan's "current" project. "A diesel mechanical switching locomotive" of Westbury design from page 11 of the current (issue 20) Model Engine Builder magazine. If you don't subscribe to that magazine, you should!
