It may be true that there are many doughboy and Disney painted German Steel helmets floating around and in collections, but experienced collectors can generally spot them when compared with a German painted period example. And similarly, there are many original examples. Check out Oliver Lock’s book Stahlschutzhelme where there are plenty of period images of camo helmets. And there are examples of of blood damaged German WW1 camo’s in collections, so this puts to bed the theory that they may not have been used on the battlefield. Many of the helmets in the video looked off to me, and the one in the thumb nail is a doughboy painted example and is also featured in Oliver Locks book.
