Could the German army have used cut away MGs for their own instruction purposes?
As for the red paint, I have a sectioned Mills bomb from between the wars, although the red paint is old I can't say for sure when it was painted.

To prove the existance of skeletonised wpns in use by the Imperial Army would be fantastic, but I have just not seen any WWI evidence to confirm.
Certainly British MG manuals start talking about DP guns in the late 1920s so maybe even our own military did not 'skeletonise' until after WWI?
So although I am hoping that this is period WWI German I cannot confirm, especially as after WWI several nations absorbed/used the plentiful stocks of captured weaponry into their own service.
