Hi all! I am not sure where to post this, and I am not sure if it has already been posted, so staff please feel free to remove or move if necessary. I found this document about 15 minutes ago while looking up what octane aviation fuel the Japanese used during WW2. Please enjoy
Annoyingly I didnt have time to copy them when I was there, and due to the virus now shut. I expect it will open again sometime, so after that, you`ll find them all there. I just copied the covers and a very small percentage of the contents so I could find them again....
