Hi, much respect to all-- these yokes were found in the attic of a 100+ year old casting factory here in Los Angeles that held accounts with Boeing and other wartime manufacturers. My untrained eye leads me to A-26 and B-26 comparisons and the "Arctic Circle" insignia I'm assuming may refer to WW2 battles in that region. But alas, I have no idea. Any help would be majorly appreciated.
