Nice and complete early M31 liner system for a M35 steel helmet executed in steel. Maker marked example to D.R.P. Schubert-Werk K.-G. Braunschweig, dated 1940 (I think!). This liner is intented for a 64 sized M40/M42 steel helmet (head size 56). Felt band is missing. The seam stitching in the rear is torn. The leather remains supple and all fingers are present, only one shows damage. Honest worn early M31 liner, perfect to complete a M40 or M42 helmet with a missing liner – so hard to find these days!
