While the colours were drying, I assembled a few other bits.
Assembled the rear wall.
The underside plate is on.
I did some weathering dustying it somewhat.
Lastly I painted primer/interior colour on some parts that go on soon plus the turret parts.
Those two plates go to the inside of the upper hull and can be positioned in two positions. Not sure which position to chose. They should also be painted green as the bottom interior.
