I spent 2 weeks going through the central stores in the military once, only went through 2 small buildings. Next door was a hanger with a basement, which only held fasteners. One of 5....... Let alone the bigger ones around that held components and other assemblies. A building with a full length 50 ton crane inside, and it was needed often. I did come back with a small book of misplaced parts, along with a large number of other part numbers of interest, like lugs, connectors, cable, lamps, along with a 100kg parcel that was originally destined for scrap when I walked in the first day. Assorted resistors that were new and unused, but which had not been ordered in decades as they fell out of the system. I spent 4 hours with my stamp and a pen signing the paperwork, it alone filled a box. When done I took a roll of plastic tubing, known as "bag any length" and sealed the one end, then filled it with packets till full, then did another as it would have been over 3m long. Then put my address on it and put it in internal mail. Arrived before I got back, and filled our resistor rack to overflowing of many values.
