Restauration project japanese 70kg bomb, help needed

Can anyone provide a detailed description of this Japanese Navy aircraft bomb? In particular the correct color tones and locations of colored markings would be of great help. In addition the correct Japanese characters would be necessary and also their location. Has anyone a detailed description of this item? Or photos of such a bomb with the original paint job on? The “TM 9-1985-4 Japanese Explosive Ordnance” fom 1953 (image is from there) is unfortunately very crude in it’s description.

Try posting that question here.


Glenn, thanks a lot, can you recommend a specific sub-forum to post my question?

The Japanese Navy Aircraft Message Board would seem to the proper forum . I have seen bombs posted here before.
