For I haven't seen a crossguard like this from the swords of either the late 3K period, Jin dynasty, or the Xianbei- led Northern dynasties after this period.

I will say the crossguard they depicted is visually very suspect for me as well. In my post I just inversed the image to make it black and white. Though there were several reconstructions graphs of Jin armor that had almost the exact same silhouettes. I have the same image in some of my generic Chinese text books about but they just have generic names like "3 Kingdoms era"- and I see this image being posted but they do it more like a visual throwaway.

Because the image was so readily found I do not know the original publisher of it. Sure thing! It's a image for reconstructed Jin dynasty (3rd century) horseman's armor readily found on Chinese forums about Chinese heavy horsemen.
