Google dit maar eens: US aeronautic first aid kit
Dit is een eerste hulp tas die in het vliegtuig bevestigd zat.
"The Kit, First Aid, Aeronautical (Medical Department Item No. 9776500), shown closed above, was a canvas bag constructed with four lift the dot fastener (LTD) female connectors on its four corners. LTD studs were permanently attached to the aircraft fuselage bulkhead so the First Aid Kit could be easily snapped down or pulled off for use.
The Kit, First Aid, Aeronautical was issued in a series of patterns. Early in World War II the kit was made of khaki canvas, had a zipper around three sides to fully open the kit, and was marked with a red cross on the left front plus the nomenclature, "Kit, First Aid, Aeronautic, US" in block letters to the right front (photo, left). A later pattern, shown in the large photos above and below this section, was of olive drab canvas, with the full zipper, marked only with "Medical Department, USA" in black block letters. A third pattern, believed to be the earliest one, was also khaki canvas, with a horizontal zipper that separated a smaller top compartment from a larger bottom compartment, not the three sided, full opening zipper of the others. Some models of the kit had a fabric carrying strap for use when dismounted from the wall."
