These appear to be fragments of calculations concerning steel materials or structural calculations related to warship construction, but the text consists only of "FOR," "FRA," sequences of numbers in parentheses, and fragments that can be read as "Tamoto, Nō," making the contents of the calculations, the parts concerned, and the quantities difficult to decipher. No principal persons, organizations, or warships can be clearly identified; the warship field in the metadata reads … card_catalog_en: "Warships and Steel Materials" [Manuscript]
