B766.  Hojutsu.  1965.  Hardbound with slipcase, 6 x 8 1/2″, 262 pages in Japanese.  Hojutsu translates as gunnery and that’s what this book is about: matchlocks, cannons, catapults, and more.  Black & white photos and drawings illustrate a very thorough text.

The slipcase is dinged just a bit and there is some fading on the front cover; otherwise all is fine.  1 pound, 11 ounces.  $40.
