i believe you might be right in saying that the one pictured on right side in this photo is a dummy grenade but the one on the left side and possibly the second one has has a split in the top handle where you can put a fuse n powder my two stick grenades along with the whole grouping belonging to a viet cong bad boy black pajamas rubber u.s. royal tire sandles and his ammo pouch and nva canvas belt n hat plus i believe capture papers pictures of all that was captured at this time great grouping getting back to stick grenades i humbly believe these were used by the nva army and the viet cong bad boys hope you agree have a great day andy militarynut
