Hi Steve. Wow that's a lot of progress. It's an impressive set of views. The realism is excellent and the detail incredible. The mid level views have that nook and cranny look with much closeness, it's complicated in there. The air shaft development is a good addition.
The bits are few this time: The teeth in the refrigerating engine flywheel are so fine that at first I thought they were grooves. The chrome on the engine reverse shaft looks neat but is maybe more shine than we need. The vent duct elbows over the aft top of the engines are probably a lot tighter radius. The flex joint disks in the LP exhaust would be riveted at the rim and at the pipe flange. I think that makes 40,100 rivets.
My own view for the starting platform controls is to stay with the Belgenland style: -aft column: telephones and winch aft -middle column: desk facing aft, 4 telegraphs facing the desk, 2 clocks and the temperature reading box -forward column: gauge board, boiler room controls and winch forward. I'd only put about 5 gauges on the board. Note that in Ralph's destroyer picture there are 4 telegraphs (2 black/silver), a rev counter and a clock so there are only 6 main gauges left.
