May 2, 2014 is the first day of the spring auction at the Rock Island Auction Company. There are lots of historical, collectible, and beautiful firearms up for grabs this year, but this one caught my eye. Dubbed “Hitler’s Buzz Saw” by WWII soldiers, this German MG-42 medium machine gun was used by the Nazi forces throughout the second World War. The design was easily produced, innovative, and effective, the Allies copied much the weapon to create the M60 machine gun. The specimen on sale is outfitted to be used as an anti-aircraft weapon with a mount, anti-air sights, and optical sight.
