German WWII Army M1940 Steel Helmet, Q64

Original period manufacture. No decal M1940 steel helmet with original paint on the shell. Maker marked on the rear of the neckguard Q64, with a lot number of N525. Rough finish dark ordnance green paint on the interior and exterior of the shell. Original German leather liner & band which I believe came out of a Norwegian capture helmet due to the color of the leather. Slot washers are in place on the rivets. Original German chinstrap, stiffened from age.
