that was actually my second go-to internet source. i had a couple of books as well, but when i needed a quick reference i went to that and this: http://www.sengokudaimyo.com/katchu/katchu.html
there are a couple of english-language forums for people who craft their own japanese armors -- mostly for SCA -- and they were very useful as well.
i do intend to add nanban armor, as well as all kinds of kawari kabuto helmets. i'm unsatisfied with the current naginata models and i'm currently working on that right now, as well as a full suite of new yari and yumi models. oh, and a new tanto -- the current one was a hastily shrunk-down katana model i pulled from runico's OSP that i had been putting off to replace since 1.0
basically, last night, even though it was a weeknight and i had work in the morning, i spent time on the new katana, tachi, nodachi, and wakizashi models. there are two sizes of wakizashi and two sizes of nodachi from this point forward
