Great topic. This should be pinned. I read somewhere where some of the INLAND stamps were stamped backwards, frontwards, and sometimes both on the same liner. :think:

[Bugme]

Here's a double stamp image of an Inland mold that made it's way to Firestone where their stamp was superimposed over the old Inland stamp.

Here's a nicer example of the actual Hood Rubber logo:

On the Hawley helmet liners that were sub-contracted to General Fibre Co. you'll also find a simple 'G' stamped somewhere near the crown. This is an image of an actual 'General' stamp.

Thanks for the liner manufacturer identification stamp information. This really helps to tell who made my liners. Is there liner identification stamps for liners used in KOREA and VIETNAM? I have not found any.

Capac is definitely the most dangerous one if you collect wwII stuff.

 

I got fooled once and it immediately went back.

 

Wouldn't buy them anymore.

 

I do have a Seaman liner if you guys ever need pics on that one.

What do you mean by Dangerous... I have a Westinghouse/Capac double stamp so I'm curious.
