The Fireman Grenade is a compact, cylindrical explosive device with a brass casing adorned with intricate Art Deco engravings. The top features a small, domed ignition button with a red enamel finish, surrounded by a ring of cog-like detailing. The body transitions into a darker, oxidized copper base with visible seams and rivets, emphasizing its steampunk construction. A series of small vents near the bottom suggest internal combustion mechanisms, while the overall design balances functionality with ornate decoration.
