This book "Engine History of Nakajima Aircraft (265pages in total)" consists of two main parts.
Development history is described on the former half with many engine photos.
Memories, recollections and testimonies of the former engineers occupies the latter half with almost no photos.
I introduce the photos from the former part and the chronological table of engine development history along with the full engine lists of Nakajima from the latter half to refile to 54 pages.
Publication of this book was discontinued twenty years ago, so I believe this is a rare opportunity to check its contents.
