Uncle Charles's job at the first of the occupation was to mismatch rifles. His fitness report depended on the number of matching rifles found when they were handed out to the vets at the end of the voyage. The more matching rifles found, the more black marks against him. That is the true and correct reason why they are are so many mismatched rifles. Unk. did a pretty good job and was awarded 20 points towards his early release from the Navy.
