Sinric has quite decent patterns.
I enjoyed making his italian legs and breastplate some years ago.
You find his site at:
http://www.eskimo.com/~cwn/
Helmschmiedt's sitye is also usefull, but it's a russian site in Cyrillic.
Anyway you can reach those very, very, very slow-loading pages at
http://helmschmiedt.narod.ru/technology.htm
I found his patterns very usefull, but sometimes a bit oversized and over-scaled.
So when making his " Schaller" helmet It came out way to big, so first make some paper dummies and look at pictures of the original ones in order to make some modifications to the pattern.
By the way, you can translate the cyrillic pages by the use af Altavista's Babelfish free online (URL based) translation tool.

Only the page are so, soooooo slow that you cannot translate them from the original location so what I did was to download all of his pages, copy them to my own website space and translated them there.
Some quite clear English came out of Babelfish, with some funny bits in it.
