German WWII M1935 Double Decal Luftwaffe Helmet, Unit Marked Liner

Original era manufacture. NS64 marked shell, with original decals as shown, fairly clear 1938 oval stamp inside the crown. Original liner with all three rivets present with slot washers. The liner is intact but dry, no fingers have been pulled through, and the adjusting string is present. Interesting unit markings are stamped on the underside of the liner.The chinstrap is in poor condition, broken on one side with a postwar repair on the other side. Otherwise an honest original helmet.
