I just saw an announcement about a forthcoming book: The Funeral Achievements of Henry V (info here). It's a pretty heavy-hitting list of editors and authors and looks like quite interesting. I pre-ordered a copy. I signed up for their newsletter, which gets you a 30% off coupon code. :) The chapters by Tobias Capwell (helm) and Robert Woosnam-Savage (the sword) are of particular interest.
