Undated but listed as Bakumatsu era two-volume manuscript set on the forging of matchlock firearms and cannon (as described by seller). Particularly interesting in that the tools used in the making of these weapons are illustrated and described.
The seller's write up is a little obscure, but I believe it states that volume one is 74 pages (37 leaves), and volume two is 78 pages (38 leaves).
Condition: Fair - aged, stained, wear, water damage.
Auction ending: Nov. 4
