Firestone Liner question

[mansioneer]

Hello Gentlemen,

I was wondering if there's a chart showing Firestone M1 Liner dome numbers by production date. In particular, I was wondering if a Firestone Liner marked "54" is a factory control number from WW2 or if the number is an indication of the year?

Thanks!

Good question, I'd be interested too.

As far as I know, WWII production liners had different numbers stamped near the logo which represented the mould number for quality control (The M1 Helmet of the WWII GI by Pieter Oosterman goes into great detail about this). I know that Korean war Westinghouse/CAPAC liners utilized the 51, 52, and 53 numbers as per 1951, 1952, and 1953 dates since one made the liner and the other webbed it. Beyond Korean war I'm not familiar with liner markings...

I did not think Firestone made High Pressure liners post 1945. The 54 would be a mold number. I do not know if they can be dated based on that number. The components of the liner seem to be more accurate method in dating them.

Thanks John!

Firestone made liner even after 1945. Therefore a picture of the liner in question would always be better.

I am interested to learn more about post war production by Firestone. It was my understanding that CAPAC was the only producer for the Korean war era helmets.

I sure can, here are a couple. The exterior shot of the liner is so low resolution, it wouldn't help to post it here.

Thanks!

Looks like a good one to my eyes. There should be some markings on the back of the nape strap and on the cloth of the sweatband. No need to remove sweatband as they should be on the cloth by the adjustment.
