Please help identify these bullet casings

[Brian T]

These were reported to be recovered from a WWI battlefield.
If you can tell me whom they may have been fired by, that would be very much appreciated!!!

This is what I can tell you on their dimensions:
Height: 2.26 inches (57.4 mm)
Radius at the base: 0.47 inches (11.9 mm)
Radius at the top: 0.37 inches (9.3 mm)

Here are the head stamps

And for what it's worth, the view of the opposite side.
Thanks again,

These appear to be German 7.9x57mm cases made in 1915-1917 by Spandau arsenal....Pete.
