Hello all,
you are surprised of this pipe plug in the nose !? Well, I have probably an answer.
Like Kgr says, this bomb seems to be a french WW I bomb. I can't post a picture today, but I'll try it during the week. If you could post the dimensions, I should post the correct picture or drawing. In this type of bomb, the frenchies had three models : 10, 25 or 50 kg. These bombs were loaded with a liquid explosive : anilite, mix of petroleum and another component that I don't give the name because the rules of BOCN do not autorize the compositions of explosive !!!
This type of bombs were used 22 june 1916 on Karlsruhe. 40 bombs were dropped and caused 800 death with a big blast effect.
So ! You known now so much as me. Post the dimensions and I shall post the pictures or drawings.
