Yes, am aware that some parts isn´t in production anymore, and others (as already mentioned) not allowed due to today´s safety regulations.
What i was referring to, was the nickleplated parts which they still make in house, like steamlines, cylinder end covers, oilerlids...
They could just as well have used them BEFORE they were nickleplated, to get a more historically correct rendition of the original.
I noticed in the pictures the nickel steam lines, whistle and regulator. All of these are on other engines
currently in production and would have looked a whole lot better. They could have used some of the engine
components like the flywheel and connecting rods from the D21 also. All silver out, brass in.
