This book has around 50 pages with writing on them, I am not an expert on what topics there are but up front appears to be a code descrambling system with numbers and alphabet, then on other pages appear to be bombing instructions for a bridge and a hand drawn map with a fly pattern with possible drop or check points, in another area appears to be like a morse code with short and long lines each associated with words. I do not read Japanese so these are my guesses. The book is guaranteed old and authentic and came from a very respected and well known war memorabilia collection. This was likely taken as a war trophy by an American soldier after they came across the body of the pilot, or shot him down. The book was inspected for war secrets as noted by the joint intelligence inspection stamp on the inside which is signed by an American officer. I count around 50 pages with writing and many more that are blank. The binding is in very rough shape. A truly one of a kind piece that exists nowhere else.

I did contact an independent translator at one point, and this was the reply, so would need someone with a historical background to translate:Thank you for your message but the entire book is written in this unique style ( we don't write things in such style nowadays) and because the images are quite grainy it makes it hard to read and translate. I can try working on some pages but I think it will be quite difficult, I also see words which I can read but have no idea what they mean
