Two books: "Zoku Bunsho Kihan Kōgi" (14th edition, Meiji 42) and "Sei Bunsho Kihan Kōgi" (17th edition, Meiji 43). This is a reprint of the "Revised and Enlarged" edition, first published in Meiji 36. These items were kept in our family's possession, but their condition is poor (please refer to the photos of each part).
