No intention to distort your position Brian, I habitually edit my quotes because I'd rather do that than quote too much or stuff that isnt relevant to what I want to pick up on. Nevertheless, my apologies if you felt that was what I was doing.
That said, I'm still not sure of the significance here. Very few RTR models are laser scanned because of the expense anyway, but if I was scratchbuilding a model, I'd use drawings which I'd then cross-check against as many photos from as many angles as possible. It surely follows that that is good practice for an RTR manufacturer?
Again you've lost me, I still dont think you've answered my question. What relevance does this have to the errors under discussion, with the headcode panels or fan grilles? Why do such well-nigh unavoidable compromises with track-related factors have a bearing on the acceptance of discrepancies in the upper bodywork? We also typically accept reductions of maybe 50% in platform length, does it follow that we should be prepared to accept a hypothetical Bo-Bo diesel that was a scale 25ft long, if one were made for us? I'll repeat, I dont expect any model to be perfect, but I also dont expect anybody to be holding back standards, either in RTR as it comes or in the efforts of those who see it as a basis for improvement.
(I should no doubt make clear that this is a general discussion of principles now, FWIW the errors on the Baby Deltic wouldnt bother me).
