At Tets Research Institute (reported here in June 2017 and March this year) Tetsuya Inoue has continued his awesome, painstaking and ultra-realistic 1/48 scale model engineering project with an update (and additional images) here. Tetsuya's work in recreating the propeller hub assembly (below) has to be seen to be believed.
Truly outstanding work. With thanks to Tetsuya for sharing it with Aviation of Japan.
