Here are some images of my scratch/ kit bash 1/72 scale Post Apocalyptic Submarine.
This model was built from the other Trieste II DSV kit. The remnants of
two ME 262 jet engines, a TV aerial, the rudder from a HE 177 and
various sundries of greebling and wotnot.
The two main things in my opinion that are important when creating post
apocalyptic machinery is that it must look like it was put together
piece meal, as one would expect to see in a post apocalyptic
environment. The second thing is that they must have a face. I feel it gives an addition of character to said model.
