Here is a excellent link to the National Museum of Japanese History, there are some rare prints showing how a Japanese matchlock was manufactured along with some other information, and a link to a Wikipedia article I wrote on tanegashima matchlocks.

Fean, as far as I know all there were no brass/bronze tanegashima, but the Japanese did cast small brass/bronze cannon with were ignited by hand. At least some of these types of cannon (taihou) were used for firing bo-hiya (fire arrows), these are called "hiya taihou". This image is a small cast brass/bronze hiya-taihou loaded with a bo-hiya.
