I have 2 of these pamphlets. If you are a military vet from back in the days of Vietnam and shortly after, you would remember these, especially if served in the Army. Title is "The M16A1 Rifle, Operation and Preventive Maintenance." They are the old comic books as people called them then, with a publication date of 1Jul69. These are still in the plastic sleeve, with 1 of them having a small hole, about the size of a .17 cal, in the plastic in the corner of it. These could be considered collector items as such for the serious collector. Price is $27.00 shipped priority mail for the pair. Email or IM if interested, and thanks for looking.
