The label does not say M65. The label usually says COAT COLD WEATHER 50 Nylon/50 Cotton. There is usually a NSN or NATO number plus a DLA number which is Defense Logistics Agency plus name of contractor plus user instructions on label. Older Vietnam era olive green ones usually have a DPSC DEFENSE PERSONNEL SUPPORT CENTER number and sometimes the user instructions are sewn inside at the bottom of the coat. If you run across the older green jackets there are variations amongst them as I think the Air Force had a slightly different version at one time. Coat is very hard wearing and well worth the search for. Watch out for liars...once had a salesman try and sell me one saying that this is an authentic combat jacket as used by the Yanks and very hard to come by in the pawnshops...but there were no pawnshops around and inside the jacket label at the bottom had HONG KONG on it. I was polite and left!!! Check out flea markets and secondhand clothing and army surplus stores..once you see a few real ones you will know what you are looking for and good luck!
