B737.  Nihonto Koza.  Volume 7, kodogu.  Various authors.  1970.  Hardbound with plastic jacket and slipcase, 6 1/2 x 10″, 422 pages in Japanese.  Tsuba, menuki, kotsuka, & kogai in photos and the occasional drawing: this is a great reference.  I have also, at the moment, the complete 10 volume set in Japanese and Harry Watson’s translation to English of 6 of the 10 volumes.

Other than a gently bumped corner on the slipcase and a tear in the plastic jacket, condition is excellent.  2 pounds, 12 ounces.  Was $65; now $35.
