I'm guessing German Navy on the right, German Army on the left. German Army during WW1 in 1914, had helmets similar in looks to the German Army of WW2. This could be, as you say, early 1900s. Before WW1. I'm guessing remember?
The coal shuttle helmets didn't come along until 1916, prior was the spiked Pickelhaube.
