Further research into helmet decals is the tri-color was no longer put on them after 1940 so maybe I should just paint over that side. Repros show them but they also use decals which were never used for the DAK emblem, all were hand painted.
One helmet is showing a D with a line through it in place of the tri-color as a unit designation and this is white painted over the sand color.
I'm also thinking I should tighten up the paint around the tree to make it less green

Behr flat latex enamel. Basketry is the color. They make up little plastic containers of it to use as samples. I could still probably paint 20+ helmets with it.
What about sand? I've seen a couple of originals that look like they mixed sand in the paint.
