Mill Stamp ID's

[maltby]

Hi,  Please forgive me, I'm a newbie. Hopefully someone can help.  I have two log stamps that were meant to imprint the name of the company that sourced the logs.  They are AK & TCI.  These came from the Pacific NW, although that's not the final proof of where these companies originated.  Any ideas?

     Here's one place you can look, but I think it only covers Washington brands.
