Hello, I am considering purchasing the projectile in the attached photo that is up for sale in NZ, and was just wondering if anyone has any idea as to what it is and its age ? I'm told it is 4.3 inches (11cm) diameter, 19.3 inches (49cm) high, weighs about 10 - 15kg and has no 'insides'. How likely is it that the fuze would contain any nasty explosives ? (sorry if this is a dumb question !, I'm a bit paranoid about aquiring something dangerous).
