I noticed there are two plates in the 1459 Talhoffer (see Jeffrey Hull, pages 259-260,
http://www.thearma.org/Fight-Earnestly.htm) that show basically the same technique shown on pages 7 & 8 of the I.33 manual (see Jeffrey Forgeng, The Medieval Art of Swordsmanship,pages 32-35; see Freywild, 4r (7) & 4v (8),
http://freywild.ch/i33/i33aen.html#16). It is cool to see the images of the same sequence of actions from two manuals 100 years apart correlate so nicely. The Talhoffer images also suggest that opposition guards in I.33, such as Krucke, are dynamic in nature rather than static as I have seen in some interpretations outside of ARMA.
