This was part of the Apocalypse releases.
Having (eventually) got the model out of the blister you have a better idea of how many parts you get in there.
The next stage was putting it all together, I decided to put the whole model together as separate assemblies didn’t seem to be needed.
The rear view.
The next stage will be a black undercoat.
