A useful picture jcb 3c, interesting to see the two railway vehicles have gray roofs, would this have been a translucent material to give light inside or was it just under coat or unpainted? Model manufacturers mostly paint the roof body colour, an easy improvement would be to paint and weather this to more resemble the real thing.
Merfyn, good to see pictures of your models again, I would be interested to know what smaller wheels your Karrier Bantam cab unit uses, it has been said on another forum that this model was stretched scale wise to fit the standard Base models chassis and is nearer S scale than 00.
