    Fiber liner construction:
    These were made from a pressed fiber sheet formed into the shape then then painted green on the inside before being covered with a thin fabric.

    Low pressure liner construction:
    The St. Clair Rubber Company and Hood Rubber Company developed liners that allowed for quicker or cheaper production and distribution. The “St. Clair” was a low-pressure plastic liner that used short steam pressure to mold the duck cloth and provided a means for a much quicker production. The St. Clair liners are easily identified by their shiny plastic appearance and indented sides. The low-pressure technique used by the St. Clair firm did not perform as well as the high-pressure models, and their contract ended in early 1944.

    High pressure liner construction:
    The high-pressure technique basically included the following steps (which varied depending on manufacturer)
    1. Duck cloth saturated in plastic resin.
    2. Duck cloth cut into strips and made into pattern.
    3. Pattern placed in hydraulic press mold and formed to shape.
    4. Excess rough edge trimmed off and rivet holes punched.
    5. Suspension system and chinstrap studs riveted in place.
    6. Painted olive drab and baked dry.

    Could be possible, but I think this is simply a personalised US Navy helmet.
    The US Marines have an 'EGA' ( Eagle, Globe, Anchor ) logo.

    There were US Marines present at D-Day in Normandy, but apparently
    there were very few ashore. I do not know where
    or when they landed...............
    Regards,

    Great resource Nick, thanks for your time.

    Can you tell us in the case of Capac liners the significance of the single digit near the Capac cross? One of my Capac liners has the numeral 6 (or is it a 9)?
