Just noted a group which seems to have found an 1933 manual for the "dadao", the munition-grade two handed Chinese sword used in the C20th by the military. http://www.chineselongsword.com/dadao.shtml
They charge for the download, but there are some pics and translations from the manual, which give a sense of the instructions and illustrations. Basic guard seems to be "Vom Tag". I thought this might be interesting.
