Martin, I cannot thank you enough for going into such detail with this information. I have always had to rely on the few references I have to find any data on these arms, which as I have noted are not areas I have studied in any notable degree.
Having your insights is most valuable, and trust me I am feverishly taking notes!
I truly admire your expertise, and Changdao your input as well! you guys are a great team.
I hope more examples will come up here, and that this thread will evolve into a comprehensive look into the swords of these regions. These kinds of threads with focused discussion are what these forums are all about!
