The 186th Infantry Regiment was the Oregon National Guard's contribution to the 41st Infantry Division, a formation comprised of troops from Oregon, Washington, Idaho, Montana, and Wyoming. The 186th saw combat in New Guinea, Biak, and the Philippines. This may very well be the only HQ Company guidon from the period still in existence. Any research regarding the fates of the other company guidons from the regiment have turned up empty. I don't know what my buddy paid for it, but all I can say is he scored a magnificent deal.
