37thguy Posted May 6, 2010 Share #13 Posted May 6, 2010 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: Link to comment Share on other sites More sharing options...

Watertown, Massachusetts Identified by a silver "HR" in the crown 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. Link to comment Share on other sites More sharing options...

ken88 Posted July 18, 2011 Share #24 Posted July 18, 2011 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. Cheers Link to comment Share on other sites More sharing options...
