That's pretty cool! I picked up a FAK a few years ago that was army surplus (probably Vietnam era), and the contents were pretty interesting.
I gotta say, though, that the hanging kind of makes sense, even if it IS a stretch. Boy Scouts DO rapell, after all, and with all the knots, it's concievable that someone might get tangled (esp when the kids are goofing around).
I don't think bandaging has changed much since the Romans

Thanks for the pics; I'm amazed at how intact everything still is!
