Well, Matsumura Kenpo is a Shorin-ryu style, use of the word "kenpo" notwithstanding, so it falls under the category of "Matsumura Shorin-ryu" just as much as, say Kise Fusei's Kenshinkan or the late Arakaki Seiki's Shinbukan (I think it was "Shinbukan"). Don't let the "kenpo" fool you into thinking it's a style like Tracey's Kenpo or some other such thing. Matt, Curt is still making kobudo gear and getting better and more refined all the time. I'll dig up his email and send it to you privately. He used to have a little page attached to the Seattle Kobukan, but since that site's gone down I believe Curt's page evaporated as well. For those of you curious about Kuda no Tanmei's Okinawan MA training, he engaged in sumo as a youth (which is different than the mainland version), Shuri-te from a fellow naval conscript, allegedly some bojutsu from his father which influenced the bo kata of his kobudo system, Kobayashi for a short time under Nakazato Shuguro, Okinawa Kenpo under Nakamura Shigeru for long enough to earn his shihan menkyo, and finally and probably for the longest amount of time under Soken Hohan. He and his son, Tomosada, also briefly participated in a study group with other old-style contemporaries after Soken's passing (Higa, Uehara, Nagamine, I forget who else in that group, I'll have to ask when Tomosada-shinshii is back in the states)... concepts and bunkai only, apparently there was no "kata trading".
