I have a box the size of a mini-fridge with old kit boxes inside divided into allied, axis, Great War, clear parts, underwing stores, and un-built phased out kits. Beyond my self-diagnosed obsessive-compulsive disorder which prevents me throwing out anything that might someday prove useful, I watch the "looking for" posts on the hobby forums for any chance to find good homes for all of this stuff. As though a sprue of USAAC drop tanks was a puppy up for adoption or something.
