Fair comment, Junctionmad; better a tartan one that can be repainted in the jhb171 tartan, or oldBlarney tartan, than none at all.
Someone mentioned cab height. Yes, they were a good foot higher. I footplated one years ago which was part of a pair (B130, I think). The other loco was a 141, and from sitting up there in 130's cab it looked shrunk!
In model form the difference will look even more stark, I would imagine, as the modeller is looking at his models from above, rather than platform or ground height. That photo a few posts back is taken with a long telephoto lens, so exaggerates it to best effect. In reality they didn't "look" as tall as that, but there was certainly a difference of a foot in height, I'd guess. Lovely engines.
(Often wondered what one would be like in plain green, but let's not go there!)
