Here are some good links that show a diagram on how early arquebus and matchlock firearms look like during the time. One of them is diagram of a Japanese arquebus called Tanegashima that the Ashigarus used in battle during the Sengoku Jidai: www.geocities.com/Yosemite/Campground/8551/firearms.html www.geocities.com/Yosemite/Campground/8551/ core.ecu.edu/hist/tuckerjo/arquebus.htm One of them is a yahoo site so it won't let me hotlink the pictures and I don't feel like copying the pics and uploading it to imageshack.us or photobucket! Just check it out.
