The deep brown shade of the 6d has a slight aniline quality, and has a tendency towards ink stripping; the deep brown is the scarcer of the regular non-variety issues.
The close-up of the horizontal line joining rifle to the middle soldier's leg can be seen in the previous post.

"The deep brown shade of the 6d has a slight aniline quality, and has a tendency towards ink stripping", slight aniline quality (aniline is an acid, would that account for most of the ink stripping)? Any indication if the gum is affected by the aniline?

Yes, it can cause ink stripping, but this was not something happening when aniline ink was used. Aniline ink was rarely used in the printing process of stamps, as this was an expensive experiment and eventually discarded, the gum should not be affected by the ink as shown by the backs of both a regular 2d and one that is aniline.
Ink stripping was caused by not enough ink being supplied and the doctor blade removing and/or spreading an inadequate amount of ink to cover the plate.
If the affect to the gum means that the aniline will soak through the paper, yes, as shown in the image on the left the ink gives an appearance of an off-set to the gummed side.

A very scarce collection of the 1940 A.I.F commemorative printing. Included with this collection is the unlisted 2d carmine with aniline ink, 2d carmine dry ink and 3d blue with a horizontal line joining rifle to the middle soldier’s leg.
The deep brown shade of the 6d has a slight aniline quality, and has a tendency towards ink stripping; the deep brown is the scarcer of the regular non-variety issues.
