On this edition of Curator's Corner, John Popp joins National Firearms Museum Senior Curator Phil Schreier to talk about a World War II-era M3 Submachine Gun better known as the "Grease Gun" due to it's similar appearance with the old-fashioned tool used to lubricate automobiles. Developed throughout 1942 and used up to the Gulf War in 1991, the "Grease Gun" is a very crude but maneuverable design. It weighs only about eight lbs. and is easy to operate since it shoots slowly and accurately. Originally aired 9/9/2010.
