Agreed and I wouldn't be surprised if there was a range of favourites if everyone was asked!
Making a sweeping generalisation, many modellers are of an age where mk1s are incredibly familiar, even without having cause to have studied them. I suspect we'd all get close to estimating the door window size fairly well for example, having leant through them 1000s of times (or is it just me?!)
So we probably have a firm idea in our minds of the coaches and hitting some key characteristics would determine if a model "looked" right.
I accept there are constructive observations around details but compared to what has gone before, i'm hoping for something where at least the fundamentals are right.
From what I've seen, which admittedly is restricted to a few photos so far, these coaches still have potential in terms of the overall shape and feel?
