There are many amateur designers in Russia, that works in different areas of interests, and some of them do some WW2 stuffs (or stuffs, that looks "like ww2 vehicles").

- Other enthusiast restores real T-34 tanks from small parts and scraps, which have been found on battlefields. Those small parts were formed after T-34 tanks were hitted by enemy fire, and then were exploded by explosion of own ammunition.
