Hi all,

I present you this item hoping someone will know what it is. It has been found empty in the presence of explosive charge of black powder.
The body is made of glass with a constriction at the highest. The neck receives a metal part by screwing.
The total length is 385 mm. The widest diameter of the metal part is 87 mm. The inside diameter of the neck is 35 mm.

Thanks in advance.

M.

Nothing familiar, how was the BP charge configured?
