Named NS64 M40 Heer ex wintercamouflage overpaint with rare Feldeisenbahn unit ID

Very nice and original M40 Heer ex winter camouflage overpaint helmet. Nicely marked NS64 indicating production by Vereinigte Deutsche Nikelwerke, Schwerte. The helmet is complete with its original factory fitted spliced liner. The liner is named to W. Johannsen. The helmet retains up to 85% of its external paint and 70% of its period lacquered decal. All in all a very nice and rare helmet in very good condition. The liner is named but also feldpostnumber marked 46842 indicating a railroad unit which is very hard to find!
