If I had started scratch building a comparable model in the Pleistocene Era, I would only be half way through, today, 2015! How do these craftsman do it? How do they paint it? How do they research it? How do they solder it?
Einstein said the only miracle he was aware of was compound interest. If he had lived to see this model, he would have cited it as the second miracle. Simply perfect!
Oh, the scale profile wheels gauged 5 foot is a nice touch and I hope it becomes more the rule on high end brass.
