Here we go to get shot down, Foreground, Dodge dump truck, behind right a Bedford OYD,folowed by a Dodge D60L followed by a GS Ford, with another Dodge D60 facing the railway and a 4x4 GMC reversed towards the railway.I think the sign says 40 ASP, I can slso see a Road Roller posibly a Greens or a Marshall, behind the CMP 4x4. If the railway engine is a 2=6=0 layout a contender would be the Class 545 engine built by two companies in the U.K. and one in Germany to the same design. There is a good picture of a Dodge dump truck on page 33 of the December Windscreen.
