And here it is!
In 3 weeks from boxed and not assembled to painted and weathered!
I must admit that the cleaning and putting together did take a week on its own. and the last week was less intense due to resuming work.
I could have done it in two weeks if I did not have the gaming weekend with the friends and then went away a few days too.
However, if prior to my holidays I would have assembled them. I could have done those 21 tanks in a week O_O
