AFAIK the most common Italian WW2 bomb, used in all of their bombers like the S.79, Z.1007, etc. Scaled 1/72 (assuming the real bomb was 130cm tall). I am not sure about the shape, perhaps looks slightly too slim compared to photos, but it is made exactly according to drawings I have found. Let me know what you think.
