Nice. I expect some 11CVs to be appearing as scenery.
I have only just noticed, but was the tank assembly instructions created by a different person to the 11CV instructions? I ask because the alternative gun assemblies are shown for the tanks but the alternative headlights are just described not shown.
Actually while writing this I noticed that the two tanks have different styles of instruction for the turret (because one has two turret options I assume).
All are perfectly reasonable for a model of this kind and (with the exception of not showing what the two headlights look like, I assume that they are numbered on the sprue) should allow their assembly with no problem.
