WW1 German Camouflage Helmet Named With Research to A Soldier Reported Missing 1918

An impressive & informatively researched M17 camouflage helmet to an Infantry Feldwebel Leutnant who was reported as missing in 1918.
Helmet bears a three colour tan ochre, brown & forest green segmented pattern with black dividing lines that create a very effective camouflage pattern. Thick brush strokes are still very much evident to its entirety with all three of the liner pins totally original to the shell. Interior has metal band of the M17 with one pad holder remaining. The clear handwritten rank & name of ' Feldw. Lt. Lange ' is visible to the underside of rear rim which has revealed the following information upon research :

Feldwebel Leutnant Lange , 2nd Coy , Res Ersatz Inf Regt 3 & an experienced NCO promoted to rank of Feldwebel/Leutnant .

Reported Missing Sept 1st 1918 , Morval.

I have enclosed a photocopy of the 1918 records with the helmet.

Fascinating piece of WW1 history & perhaps a souvenir liberated from a casualty that was never found.

Heinrich Lange from Halle & born December 6th 1876.
