*German, c.1940, M40 Stahlhelm Single Decal Heer Helmet, ET66, Lot 312*
Original German World War II M40 steel helmet (Stahlhelm), single decal Army (Heer) example. Early M40 pattern with factory-stamped ventilation holes and rolled edge. The shell is stamped ET66 to the inner skirt adjacent to the chinstrap bale, indicating manufacture by Eisenhüttenwerke, Thale, size 66. The rear inner skirt is clearly stamped with lot / batch number 312.
According to Brian Ice, German Helmet Lot Numbers, Revision 9, ET M40 helmets within the 1–9999 lot range belong to the second M40 production group, estimated late November 1940 to approximately August 1942, with the earliest sub-range (lots 1–500) dating late November–December 1940. Lot 312 falls firmly within this earliest M40 production window. The exterior retains its original rtgg (rough-texture grey-green) field-grey paint, showing heavy but honest service wear and surface oxidation. The left side bears a single Heer decal, worn but clearly identifiable. From March 1940 onward, most M40 helmets were produced with only one decal, making this configuration correct for the period. There is no evidence of repainting, artificial ageing, or post-war restoration.
The interior retains its original ZSH configuration, comprising a zinc-olated steel liner band fitted with a period sheepskin-media liner (contemporary documentation lists leather, sheepskin, and goatskin under SH). The liner shows correct age-related wear, including dryness, sweat darkening, and surface deterioration consistent with wartime use. Original drawstring present. A liner segment is stamped “58”, indicating liner size, consistent with fitment to a size 66 shell.
The interior dome retains a faint, partially legible oval ink stamp, with only the terminal letters visible, ending in “…ch”. This is consistent with period factory or inspection markings and is worn, as commonly encountered on original helmets.
Historical Note: The M40 Stahlhelm was introduced in 1940 as a simplified evolution of the M35, replacing separate ventilation fittings with stamped vent holes to accelerate wartime production. Helmets produced by Eisenhüttenwerke, Thale (ET) were among the most widely issued during the early war period. Following regulations introduced in early 1940, the national tricolour decal was discontinued, and helmets were thereafter produced with a single service decal only, as seen on this example. Helmets retaining untouched paint, original liners, and clearly stamped early lot numbers are increasingly scarce.
*Condition* A completely original example showing honest wartime wear. The shell exhibits surface rust and paint loss consistent with age and service. The Heer decal is worn but original. The liner remains intact with the leather still supple, with minor expected age-related deterioration. No evidence of repainting, liner replacement, or post-war alteration observed. The helmet retains one original period chinstrap half, attached at one side, with its metal buckle present. The leather shows age-related wear, cracking, and surface degradation consistent with wartime use. The opposing chinstrap half is absent. Please see photographs as part of the condition report.
