Hello, My father-in-law was cleaning up an attic of a person the other day, and he stumbled upon the object in the picture. The object is a double metal can, inbetween there's folded cardboard so that the thing in the second can cannot break. The object in the second can is a glass tube, filled with some kind of black liquid. He found this object together with some german steel grenades. Thank you for your help!
Oi!..Your father in law is a brave man...Do you think -maybe a call to the local bomb disposal unit would be in order? Because it is probably not full of Love Potion #9 https://www.youtube.com/watch?v=7rXhXLsNJL8
