I get this tank since it looks like the KV-1S in World of Tanks. Trumpeter has a great line of KV based tanks that they offer many different versions of. This one come with a metal barrel. The instructions are easy to follow. The tracks take some time, about 3 hours, to cut, clean up and assemble, but they look great with the right amount of sag. I had to use a little putty on the casing seem of the turret where the top and bottom meet, but the real tank had this seam, so no problems.
