Thru the good offices of Grey Doffin I was able to get a nice new edition of Sawada's Koshikju Nyumon Nihon no Koju (Japanese Old Guns) and I am very pleased. This is not a gaijin friendly volume, but it very well presented with great illustrations.. As and "introduction" it emphasizes oddities, but it covered a wide range of both matchlock and 19th century firearms. It shows lots and lots of different19th century imports, Details of when and how imports were obtained seems pretty terse, but the range of imports must be fairly complete. Tables and lists are generally rather easily to approachable for folks with a bit of Japanese. I think this book deserves a spot in a collector's library.
