This is a unique find for collectors and enthusiasts of military memorabilia. The item is a vintage US Army M18 smoke grenade red smoke tube, with a metal and cardboard construction. It comes with an original shipping container, making it all the more special. The smoke canister tube is in good condition and would make a great addition to any collection. The grenade tube is green in color and bears the US Army brand. It is not signed, but that does not diminish its value.
