This is an extremely rare experimental Lug-less M18 helmet shell. According to Ludwig Baer in his book on German helmets, only about 2600 of these helmets were made in the summer of 1918. This experimental helmet was a response to the many complains German soldiers had with the whistling sound that the breeze made blowing past the ventilation lugs.
This particular helmet is not maker marked, but the inside for dome has a well defined heating lot number. The sequence starts with R indicating the steel was rolled by Stahlwerk Röchling,Volkingen. In my experience helmets made with steel from this firm are most often Quist or Eisenhuttenwerke marked. From the shape the helmet does appear to be made by Eisenhuttenwerke. Strangely the helmet is marked size 64 on the brim, but the shell actually is a 66. This is likely a factory error.
The helmet comes to you fully restored. There are several options available for this restoration. The helmet can be restored to an Imperial configuration with a M18 liner and chinstrap. A Reichswehr option is also available with a M20 or M24 liner with either a black M18 or M27 chinstrap. The last option would be a mid 1930s Third Reich transitional helmet with a M24 or M31 liner. Any of these options are available and are included in the price.
This is truly a rare helmet and a perfect option for anyone wishing to complete their Imperial German helmet collection. Grab this one now, you’ll never see another
