Black Pineapples

My MKI is full of concret and fuze without primer nor delay. And, of course, painted black.

From FM 23-30 Basic Field Manual Grenades June 15, 1942

Body, grenade, hand, fragmentation Mk.II with or without hand grenade fuze M5 (for dummy use) - Footnote stating *"Substitute for training grenade Mk.IAI*

Fuze- with or without, M5 fuze, without detonator

Filler - None

Body - Cast Iron

Radius of Burst - None

Painting and Marking - Black

Use - Training

Delay time - None

So in 1942 they were using Black grenades as dummy grenades. The Mk.IAI grenade has a listed use of Training and throwing practice.

OK, thanks for the research and info. Still confused a bit, but it appears then that my black G marked grenade with filler plug on bottom, at the start of this thread is a "substitute practice grenade" I always had heard thought that the M10A1 on this black grenade was originally supposed to be used as a HE grenade fuze, but they had "flash-by" problems and were relegated to be used as training grenade fuzes?

Is this correct now what my black grenade is.....a "substitute practice grenade"? but it is also "dummy grenade" ? and was never meant to go "POP" or "Bang" as for example a blue "practice" grenade? A soldier-trainee would just pull the pin and throw it for practice of the pulling the pin, and for accuracy in throwing? It never would have had a primer cap, fuze, det or black powder bag?

But they already had the one piece dummys for training. The only different thing it was the lever will not fly when pull the pin.
