I have made the changes marked by Mike for the 1939 version, hopefully that one is now complete and I can go play with some camouflage.
From all the pictures, there are no windows/portholes/doors showing on the bridge superstructure, which is a bit strange. There is a hatch in the middle of the bridge that opens for the coxswain to be able to view forward, hate to think what it is like in action and all closed up.
