Thanks, Alistair.
As for the engine, I plan to leave the side cowls off to allow for the insight into the engine installation.
And the bulkheads... Thanks for letting me know. Anyway, my model will be a sort of compromise between WNW kit, the LVG replica and, first of all - my limitations in imitating what can be seen in photos.
The work on cockpit continues. The kit bits are basically done. So are HGW seatbelts and some spare straps to make for the hanging for the observer's seat. There are still some bits to be added - control cables, the linkages from the left-side panel levers, fuel lines, the mechanism for camera opening cover, compass, fuel gauge, etc...
And when adding cockpit decals I also put the engine number and producer plate on its left side front.
