Title: [Hoshiyama-ryu aizusho yanogo?].
Description: n.p. 1837 (Tenpo 8) Manuscript 23x16cm plain wrapper, 12 double leaves (ie 24 pages) plus five unbound double leaves and a single sheet with a carefully measured diagram; illustrations through the rest. Dated Tenpo 8 on what must be the last loose leaf with a red seal that I can't decipher. ¶ Rocketry as weapon rather than fun, though firing off a rocket always has some element of fun. The loose leaves are clearly a continuation of the bound work - the first leaf has a repeat of most the title and we finish with a kind of colophon - but despite a few red numbers I can't swear they are complete.
