The M65 has some noticeable differences than the M43. The M65 has a zippered front and a hidden zippered hood within the underside of the collar. It also has velcro cuffs. The pockets were also closed with a press snap, where on the M43 they were buttons. The M-43 did not have zippers, nor did it have an internal hood. The hood had to be attached with buttons around the collar and shoulders epulette (sp???). It also had a button closure cuff. The M-43 was closer to the M51, where the only real difference was the zipper.
