Dear Mike,

I believe Italian Rapier Combat is close to being 'out of print' so it will
become more difficult to get from amazon, etc. You should always be able to
get a copy from The Swordsman's Shop at
http://www.martinez-destreza.com/shop.htm (or at least till there are no
more to be had).

Although not in print, you can get photocopies of over 150 treatises and
manuals from me at http://www.jaredkirby.com/rarebooks.htm

Take care,
Jared Kirby
