Likely a felddivision
-used M35 single-decal Luftwaffe helmet.
The helmet is maker-marked NS66 with lot number D13.
It features an attractive field-green camouflage finish, with the Luftwaffe eagle decal still clearly visible beneath the camouflage paint.
The liner appears to have sustained a heavy impact. The short retaining strap is torn, the buckle has broken off, and the liner itself shows signs of distortion, all of which may indicate damage caused by a blow or explosion.
Overall, this is a nice untouched M35 Luftwaffe camouflage helmet with plenty of character and strong display appeal. It is a fine example of a genuine combat-used helmet.
