Mortar bombs are ammunition

This photo caption say this US Viet Nam soldier is examining a Viet Cong mortar bomb. Does the tail boom look a bit long for a mortar bomb ?

Rifle grenade ?

Most likely something that was put together in a jungle workshop.

Not sure but it looks kind a like a chi-com rifle grenade. Haven’t seen one for decades so may well be wrong.

For me, it is a French rifle grenade Model 1948.


Here you can see one drawing.

I agree with domi.

Here the image without scrolling and searching:

Looks reasonable. Thank you. There was plenty of French ordnance used in Viet Nam.
