Luftwaffe Summer One Piece Flight Suit

Think this is Model K So/34 pattern. Suit has been modified some. Suit is made of brown-mettled impregnated cotton fabric. The two front leg pockets have had the zippers removed and the opening have been patched with same material as the suit also two zippers have been removed on side of legs, one on each side, also been patched with same material as the suit. There are two zippers one on each side of the hips with vertical fly zipper in center of suit, the large long zipper has had the zipper pull replaced, zipper is the original one, just the pull has been replaced, the original broke and is in the pocket. The inside has some small places with grey silk rayon type material, sleeve are lined with same. There is bevo maker tag dated 1942. I do not know how much this suit has been modified, but they are wartime, there are no zippers at the end of each leg, all of the zippers work. Overall very nice and would display great, does not show much wear or age. Exc. + $750.00
