I am very sorry, dear Shinpachi, that you cannot continue our research. But I, under your strict guidance...), started this discussion, and I will have to finish it. I took 2 screenshots from one book. The quality is poor, but a lot can be understood. You wrote that you had not heard of these names 1 瑞風 (Hatakase), 2 陣風 (Jimpu) and 3父父 (Tempu) for Hitachi/Gasuden engines. They are present here, both in the first picture and in the second. On the second one, fortunately for me, I found which aircraft were equipped with certain engines. Now I know that the Amakaze GK2 engine (the manufacturer's G-code is Hitachi and the letter K- air-cooled engines were designated) with the designation Ha-22, were installed on E14Y,K3M2,K5Y,K11W,Q1W aircraft. There is also a designation for army engines and airplanes, but I'm not interested in that right now... Maybe someone will need these 2 pictures, I was glad to help. Good luck.
Yes, I almost forgot...In the top post, these are screenshots from the book by Mawhinney, Robert. Japanese Aircraft Engines. Washington D.C.: NASM.
And these 2 pictures are from the book Japanese Aero-Engines, Mike Goodwin. Now that's it...)
