Pineapple practice grenade?

[USMC Corpsman]

Hi all,

 

first time poster. Have loved reading all things on this site. 
 

I picked up this practice grenade at a flea market. My understanding is it’s an MK-2 or M21 practice grenade WW2 era? Looking for any insight into what I actually have.

There appears to be an engraving of a “6” and some other letters or numbers I can’t make out on the side.

 

thank you!

Thanks for posting your Practice Frag Grenade. You have a late WW2 Mk. II, with a nice M10A3 fuse. Notice the "half moon" Striker Hinge Pin. This fuze dates to the mid-1944 time frame. No reason to assume any other period for the grenade body as well.

Besides the blue color denoting a practice grenade, the opening on the bottom of your grenade is larger than the standard threaded 9/16" hole, which would be the configuration for a grenade meant to contain an explosive load. This bottom opening for a grenade receiving a lethal load would be the same size as the threaded opening that receives the fuze.

 

Practice grenades had a cork inserted in the opening.  These grenades would contain a non-lethal amount of black gun powder meant to go off producing a puff of black smoke when used in training.

Awesome insight. Thank you for the information. 
you never know what you’ll find at a flea market. $10 well spent I hope!

Oh Yeah!  Just the fuse could bring $75.
