World War 1 German airplanes, tanks, wagons, a blimp and a motorcycle... all from before 1918

The wheel has me interested, a couple photos down this gallery is another

Notice the extremely long wagon in the middle
Check out the unusual wheels, the one in the middle with the flat plates has a story, I was reading somewhere that due to a lack of materials the Germans were innovating designs to adapt old wheels for heavier loads













Dual engines
all photos from http://momentdinspiration.blogspot.com/ and there are far more there, these are just the few that caught my attention
