One of the Russian youtube channels of Wargaming just uploaded a video of a SU-100 restoration, it took this gentlemen over 6 months to completely restore the tank:

I just love tank restoration videos, the subtitles are not the best but they are understandable, will keep my eyes on the feed and see if Wargaming uploads a English version, it's silly and a waste of a very good content if they don't.

And by the way, at 9:33, is that the Russian Robin Williams?
