Remember the Brickmania track links kickstarter project? It reached its funding goal and the first models that use these tracks are now appearing online.
These fine examples, an M4 Sherman and two different versions of the Stuart light tank, were built by LegoUli. These already were some of the best examples of minifig-scale US WW2 tanks out there and built in old dark grey to boot. This is a difficult colour to use, because all kinds of handy parts builders have become used to, such as cheese slopes, were never made in this particular shade. It is probably the closest match to the colour of the real vehicles, though. The old track shoes were a bit narrow, but thanks to the new track links, this has now been rectified.
