Starting on the Hansa-Brandenburg W.12

 As usual, nice box art. This box is much bigger and heavier than the Roland.

-And it's full of sprues.. (about nine of them..)

Starting with this one as it contains the parts for the cockpit interior,

Floor with petrol tank. The pilot sits on top of the petrol tank (!)

Framing. Oil tank in the engine compartment showing.

Partition with window between pilot and observer.

Dryfit cockpit framing. Below, map table and camera.
All fits perfectly. A bit more cleanup required, then painting time.
