Thank you men,
Not much happened. Just a few small things, in the meantime I've given a lot of thought to the color scheme of my rhinoceros.
And this is how my tank should look roughly, but at the moment I have to paint 2-3 tanks from a model building friend.
If my tanks are in the back line for the time being, I think I will only be able to start them in early 2021 that is how long my report will be frozen.
