As a side note about the WWII OD full length dip. The reason I call it that not only is the color WWII Army OD green, but also because Fred Bear's personal hunting arrows made during WWII had the same OD green color.
Incidentally, the personal arrows of Nels Grumley and KK Knickerbocker here at the Arsenal, also have the same OD green color shafts.
Of course they were all associated with Bear Archery and were all friends so would not be an accident that they were using the same or very similar OD green dip...
One might also speculate that OD green paint was also the most readily available paint color during WWII as so many items were routinely painted that color for the war effort. It is likely that most government contractors (like Bear) had some of this color on hand and used it for many other purposes, especially with so many shortages during the war.
