I've seen a number of images of the Ehrhardt EV4 (there were at least 3 iterations of the vehicle - 1915, 1917 & 1918) similar to this;

But what really interests me about
this picture are the helmets the Freikorps troops are wearing; the two at the front with the flame-thrower(?) are wearing your regular WW1 German stahlhelm; the four behind them are wearing stahlhem without the usual peak over the eyes, & they appear to have been made that way.
Anyone have any info?
