I ran across this article while searching for examples of traditional arrow construction and crests. http://willscommonplacebook.blogspot.com/2006...-1400.html

I don't know the author or the quality of his research. On the other hand, none of the claims seem to grossly contradict what I have read in respected authors (Bowyer's Bible, etc.) texts on capability of reconstructed weapons, or metallurgy of surviving specimens (swords, armour, etc.) One should be cautioned that quality of steel production increased (more mass production based, catalan forges, application of coal and good blast-smelting, etc.) near the end of the 15th century. It would be interesting to see a similar article on mid 16th century metallurgy.
