Dan,
Yes it is a Grenade from China sent to the North Vietnamese via Trucks running down the "Ho Chi Mihn trail" and fro Haiphong.
Yours is missing the cap of wood from the bottom to give them sometimes, and I mean sometimes, to keep it waterproof. Does that one from somebody else's collection?
This particuar grenade could of been filled with the following charges: TNT, Mixtures of TNT, or Picric acid, or Nitroglcycerine with Potassium nitrate or sawdust and Schneiderite. The little nails coming out are resonable because the age of this one is probably back during the late 60'0 to the late 70's.
If you were to cut it open you might find that the inner side of the actual head should be covered with Shelac(SP?). Shallaced (?) is for a certain type of charge that needs ------ ----.
If this grenade were the real deal, which it is not, here are the specs on it:
Weight: 500 g
Length: 228mm
Diameter: 50mm
Weight of filling: if it were produced with Picric Acid it would be around 99 g.
Fuzes: are usually made in the Soveit Union and they were ok for detonating the Grenades Then came the Chinese, they were giving out bad stuff to PAVN/VC. Which I could care the least.
Effective fragmentation radius is : 10m
Dano, your would be classified as the: Chinese serrerated, fragmenting, defensive stick grenade. That is all unless the Chinese called it "Type 56 grenade".
Most of time they were better suited for Boobytraps say for instace havening anything that swings, including are aerial bombs that were duds of any kind of weapon used by us.
When people were near the dentonating stick grenade it would be the same situation of using Iron as the grenade head. He will either be killed or wounded depending on how the iron goes.
By the way,
Nice picture,
