Kriegsmarine M 40 single decal helmet

Kriegsmarine M 40 ET 64 helmet. Completed with liner and chinstrap. Well worn salty liner, dated 1942 year and marked Metallwarenfabrik F.W. Müller in Berlin (F.W.M.). It may be a reissue, however the liner seems original to the helmet. The chinstrap is RB Nr 0/0750/0100 marked, but it not fit to the helmet's condition and seems that a previous owner added it to helmet. We can offer instead of this one another chinstrap -  a nice worn and fit by condition for Kriegsmarine helmet, made by G Schiele in Loburg, dated between 40-42 year, which is correct for KM helmets. Abnehmbarstempel is inside on the dome. The drawstring seems partially broken and one part is missed, but it still fit to the liner.  Helmet has one minor surface oxidation place, some scratches due of wear on the paint and decal. The decal is about 97 % present . Liner size 57.
