US Military Ammunition Box Drawing Numbers - M2, M1A1 , M19


#1

Does anyone have, or know where I can find, U.S. military ordnance drawing numbers for the following steel ammunition boxes: M2 (WWII .50 caliber box); M1A1 (late WWII .30 caliber box with tripod latch); and the M19 (post-WWII replacement for the M1A1 and predecessor to the current M19A1)? Thanks. - Todd
