Got Me Under Pressure

Big Red

Big Red here with a question from "Frank Beard"...

 So, TAKE FIVE!

Frank asks,

"Big Red, Wow I didn't know that the little man in IMP liners was actually an imp, that's cool man. What do you know about all the other marks in high-pressure M-1 liners?"

Good to hear from you Frank,

High-pressure plastic liner bodies initially met and, through continuous refinements, eventually exceeded the Army’s expectation for a helmet liner. High-pressure liners began to appear around May of 1942 but would not reach significant numbers until the late fall. Seven companies adopted the high-pressure method and through use of the Westinghouse Micarta formula would produce more than 38,000,000 helmet liners by wars end.

High-pressure liners were required to have a mark molded into the interior crown to identify the mold cavity used to make the liner and a symbol to identify the manufacturer. This requirement resulted in eight distinct marks.
