Johnson, Larry. Japanese Bayonets: The Definitive Work on Japanese Bayonets, 1870 to the Present. Cedar Ridge Publications, 1988. Hardcover with duskjacket, autographed by author, pictures are in black & white (grayscale), long out of print. I prefer this book over all others, even the later books. I wish more books could be as well thought out as this book. Will post some pictures shortly. US$300.
Markham, George. Japanese Infantry Weapons of World War Two. Hippocrene Books, 1976. Hardcover with duskjacket, almost new condition, black & white pictures, about 100 pages, still a useful book after all these years, US$60.
