If you go to the NFAJ channel on Youtube there are many videos of the Japanese Army in Manchuria in action and on manoeuvres as well as videos on equipment etc. This video is on the inner workings of a Japanese Armoured Train . But there is much more on the Channel . Unfortunately all captions are in Japanese but if you see 1932 0r 1933 in the title you cannot go wrong. Some clips have Crossley A/cars in Shanghai japanese interwar tanks , testing various A/A guns etc.
