R.Mikesh, A.Shorzoe Japanese Aircraft, 1910-1941 (Putnam)
Kishi No.4 Tsurugi-go Aeroplane
Although based on the No.3 Tsurugi-go, various changes were incorporated into the airframe of this new aeroplane. The lower wing was shortened and the diagonal struts near the wingtips were dispensed with. With overall weight and size less than that of the Maurice Farman Type Mo-4, this No.3 Tsurugi-go Aeroplane was more commonly called the Small Mo-type aeroplane.
Following successful flights, it joined others at Susaki to celebrate the 50th Anniversary of Metropolitan Tokyo. Also present were the Itoh Tsurubane No.2, Nakajima Type 3, and the Maurice Farman Type Mo 4 of the Imperial Flying Association. They all made circuits of Veno Park in Tokyo where the ceremony was held.
