Sons of Guns

Three Cannons and a Rock Star (3x11)

Air date: Sep 19, 2012

The Red Jacket crew bring an antique, blackpowder Lyle cannon back to life for Aerosmith rocker Joe Perry. But one cannon is never enough. Kris and Flem repair and then square off to prove whose WW2 cannon is better: a German PAK 36 or an American 37mm.
