If Rapido and Rails were releasing the Dynamometer car with lining then I suspect that we would still be having a discussion of the point, but from the reverse viewpoint.
Such is the nature of modellers, modelling and the difficulty of verifying issues from a distant black and white past.
Either way, I think both models look fantastic and I’m very happy with my order for the 1948 version. If the pictures are accurate, we are very lucky to have such a detailed, well put-together model - lined or not.
