Greetings mig,

The following link might be the first article on Iron Thread in English. For the price you can't go wrong. You can always check to see if some put this article up in the internet. This info was shared by Grandmaster Buck Sam Kong.

His student, Master Donald Hamby had some of Lam Sai Wing's books translated, one of which may have been on Iron thread.

Grandmaster Kwong Wing Lam published a book on hung gar. You may inquire i it has info on Iron thread.

Lastly, some kung fu schools privately publish. You have to know someone to get in on the inside track.

P.S. For good understanding between sound and healing, I recommend Mantak Chia's book on the Six Healing Sounds.
