I have glued all the semi-buried U-shaped rings on which the wires will be attached. I also added the small lever and bar that control the opening of the radiator grid. At the center, the MiniWorld Spandau barrels have been implanted into the Roden plastic breeches which fit the fuselage openings better.

The weathered fuselage, with its small rhodoid windscreen, the machine-guns and the exhaust stack. To get this "rusted metal" effect on it, I first sprayed a coat of a solid aluminum paint (eg Tamiya TS30), then I brush-painted the whole stack with red-brown enamel (Humbrol 70), and scratched the paint with a file in some areas of the part, to have the metal paint show-through:

The dirtiest areas of the upper wing (ie around the radiator and aileron horns) have been treated with oils, as well as the wheels and wheel axle fairing. I will increase the shading of the ribs later with more oil, after a coat of matt varnish:

Besides this, I've added a paved area on the stand. The pavement has been painted in various shades at random, then it has received an oil wash and pigments. The remaining area will be filled up with plaster to simulate the soil. Considering the answers I got about possible paved airfields, I changed the location of the aircraft and accessories: the plane will sit on the grass area representing the airfield, and the mechanic will be working on the other engine, on the paved area which is supposed to lead to hangers and field buildings.
