In 1981, when I was in the 1/73 Armor, out at Ft. Irwin, CA, we received a shipment of Grease Guns that were brand new along with magazines that were all in foil wrappers. They all went into the Company Arm's Room. We never got to shoot any of them and as I recall, we never went to the firing range for any small arms training. That is except when we went to the tank gunnery range and then of course we had our M-85's (50 cal.) on our top cupalla's. I think that they must've been the model with the hole in the bolt because I can't remember any bolt handle or knob.
When I was HQ HQ Commander of the 917th Support Group in Kansas City back around 1985-87, I'd kept all of our 1911 .45's in our arms room instead of turning them all in for the new 9mm's. I just liked the 1911. My replacement switched them over upon taking over though.
