I know what you mean!
I had a chance to conduct an audit of some of the US Army Museum holdings at Fort Benning...40 crates holding 1944 production M-1918A2 Browning Automatic Rifles. BAR, BAR Gunner's Belt, BAR Assistant Gunners Belt, 18 magazines, spare parts kit, BAR manual...all still packed in the original crate with the original paper wrappings. Crates of M-1911A1s, M-1 Garands, M-1 Carbines, M-1A1 Thompsons, M-191A4 machine guns, not a scratch or wear mark on any of them and with all of their supplemental gear....a collectors wet dream!!!
