I though I'd start this thread as an aid for all modelers who may have a need to see evidence of specific details, I not sure if this is the right location to post this into, maybe Toto and the Mods may like to consider having a dedicated location just for research evidence and fact finding? Anyway as folks know I'm building the North British Class 21 kit and a recent query on the build thread concerned the matter of roof panel lifting lugs and where and what did they look like. As chance would have it I found this picture which appears to have been shared across the internet via sites like Pinterest so I cannot acknowledge the original photographer, the picture is D6142 at Inverurie shed in May 1966 having recently been given a fresh coat of Loco Green paint. Now in the foreground look at the line of removed Class 21 roof panels showing rivet detail and edge strips, interestingly the radiator panel has the small foot tread fitted in front of the grill and the cylinder head access hatch (foreground right) shows small lifting hooks fitted. The roof repaint on D6142 is interesting too since it shows up the main lifting hook positions on the removable panel covering the steam heat boiler, electrical cubicle and radiator.
