While unpacking CONEX containers of M1's, BAR's, 1919's in '67 at MACV/SOG Kontum we found one barrel of M1 carbines. All the rest, carbines and M1's, were sealed and stacked in the containers stablized with blocks of hard foam. The rifles, M3's, 1911's were just in vacume packed foil/paper packages. The quality of the packing went down as the project went on and I remember that the last deliveries had just nasty rifles stacked without padding and heavey with grease and dirt. The most work went into the last containers with a diesel filled bath tubs all very nasty and a lot of the last M1's were inop from broken springs and damaged stocks. When I moved on to Dak To in Oct. they had started sorting the left overs into piles to make others run. I think I still could smell that mess for the next two months in my skin and BDU's. LOL
