Just another cool video from WW2 to watch. The Army actually had its own film studio back then to produce these. The corny acting and predictably "you got the best stuff" outcome is classic. I love this old stuff!!
I actually have a pic here of me holding a M3 .45 "Grease Gun" that appeared in a newspaper article in Napoleon, Ohio when I was in the national guard. We actually had them in out inventory as they were the weapons that were to be assigned to our tracked vehicle recovery operators that drove our M88 recovery vehicles (basically a tracked tow truck for tanks). We even took them to the range and fired them. They worked as advertised. That's me on the far left in a MOPP suit (chemical warfare protective gear).
