Mitsubishi's Codebook (1929)

I got a copy of Mitsubishi's telegraph codebook (1929), titled Wabun-Denshin-Ango (Telegraph Code for Japanese Text). I placed a search for a telegraph code on a second-hand book network without purpose and had the luck to hit on this item.
It conforms to the common codebooks at the time, with five-letter code groups and three-kana code groups assigned to the entries for plaintext in Japanese. The five-letter code groups are constructed according to four mutilation tables adapted to the new telegraph regulations of 1928.

The codebook is now described in
