When Valve converted weapons over to be compatible with war paints, a few of them got messed up. In the case of the Brass Beast, the brass support beam on the left side of the barrels, which was flatly shaded before, became smooth-shaded together with the inner side of the beam, causing it to be shaded more cylindrically instead of like a flat surface. The pre-warpaint version of the Brass Beast's model, which is still in the game's files but now unused, doesn't have this problem.

This submission fixes the smoothing groups on the left support beam.
