Cylindrical metal object resembling a small mortar round, with a tapered body and finned tail section featuring a central hole. The piece is completely inert and hollow, with no fuse or explosive filling.
The tail fins are evenly spaced and vented with circular holes, typical of practice or inert ordnance, designed for aerodynamic stability during training exercises. The construction suggests it was used to simulate the weight and handling of a live mortar shell without containing propellant or explosive components.
