Hi wlf,
While researching a knife I just bought, I found 4 web pages put up by Cassidy.
1. contains Photos of prototype knives, including the Fairbairn-Millerson, Fairbairn's own design for an improved Smatchet, both circa 1944, and, a "W.E. Fairbairn Cobra Design".
2. is "The Fairbairn Manual of Knife Fighting - William Ewart Fairbairn's Lost Classic". An apparently unpublished work.
3. is Cassidy's questioning of Fairbairn's collaboration with Rex Applegate on the design of the Applegate-Fairbairn Fighting Knife.
4. is a history of the Fairbairn-Sykes Fighting Knife and of the Castle Knife Company's production of the authorized Fairbairn Commando "S" Guard Commemorative F-S Fighting Knife.
You can find links to these pages in my post,
"Unpublished? W.E. Fairbairn Knife Fighting Manuscript Found!"

The web pages are fascinating reading. (Especially, to me, the information about the knife I just bought, the authorized Fairbairn Commando "S" Guard Commemorative F-S Fighting Knife from Castle Knife Company. It is a GREAT F-S Fighting Knife! Also, Cassidy himself is a fascinating American character.)
