G Schiele Loburg marked German M 40/42 helmet chinstrap. 1940 marked

German WW2 steel helmet's chinstrap dated 1940 and marked by firm G Schiele in Loburg. These chinstraps mostly seen on Wehrmacht  Heeres and Kriegsmarine helmets. Very nice condition, used, brown leather strap with steel buckle, with remains of grey paint on it, but most of it's gone due of use. One aluminum stud is missing, but we can add similar for free.
