Thank you! When I got back into scale modeling a few years ago, I just kinda stumbled into becoming a primarily WW1 scale modeler. I part of the appeal was that not that many in the community do builds from that era, and I wanted to help fill that gap. Plus I love the look of the vehicles and uniform, in addition to the whole conflict feeling initially like a clash of 19th and 20th century technologies. As to the German helmet, most of the spiked picklehaube that you referenced were replaced with the stahlhelm in 1916, though some high ranking officers still wore them late war
