WW1 Era G98 Rod Grenade Quadrant

[Gildwiller1918]

Here is an interesting item I just picked up, it is a quadrant for WW1 German rod rifle grenades. Not a lot of photographs of them being used, other than the one shown below. These were for the rifles mounted onto launcher platforms, not individual use. It slides onto the rear rifle sight base and is held in place by a spring mounted clip, which mine is missing.

I also recently discovered the British also used a similar type of rifle grenade quadrant. These were introduced in 1915 for all SMLE rifles and were called grenade pendulum sights. They attached pretty much the same way the German type did. So far I have not found any photos of them in actual combat conditions.

Here is the WW1 French version, which I have not seen before.
