Hi. When was the M21 first introduced? Cheers
Great photo Fragman!!!
ATTN: To everyone who thinks I talk a lot and make long posts.....you are absolutely correct. The many small details and long history of certain issues that I speak about, and try to explain to my fellow grenade collectors, CANNOT be said in one short sentence or paragraph. So grab a pack of smokes, some coffee, beer, cocktail, or beverage or snack or whatever you need, and just enjoy the ride. It's all good. :tinysmile_tongue_t:
Again...Great photo Fragman!!!, Thank you for showing this picture. That's a very rare item, especially marked M21, I want it!!! :cry: Is this canister and packet yours? I commented on one of these cans and packets before in one of the seems like 500 threads about M21's, RFX's and MkII practice grenades that have been made last 6 months
OK, first I'll answer your question so you don't have to read my "long post" ....unless you have interest in the "M21". The M21 was first introduced to the best of my knowledge sometime between 1941 and 1944, and was spoke about recently (see second thread link below) I personally think they were first designated as "M21 practice hand grenade" most probably sometime in 42 or 1943 is my thoughts.
This is just my educated guess based on my two cans that have loading dates of 8-44, and the other only known/seen M21 can (at least by me) that is dated 12-44, and was revised in some way in 5-44.
So if that M21 can says "revised" in May of 44 (5-44) then I think most probably the blue training grenades were being called "M21's" by the US Gov. by at least late 1943.
Frank, Eodtek, is trying to find definitive Gov. paperwork- minutes reports on this subject, and sure hope he or somebody finally finds this info to put this issue to bed finally.
Many here had thought the M21 was strictly a post war grenade until I showed the first one I found about a year and a half ago....and then just a few months ago I bought the second M21 I have from the same person I got the first one from. They both have the same 8-44 dated cans as you can see in pics below.
I've always thought that all the WW2 blue practice grenades came fuzed sealed in their M41 cans, But Not loaded with the black powder packet and no corks installed. And that the practice grenades were shipped with 24 grenades to a wooden crate, not 25 like regular HE grenades.
The reason only 24 grenades to a wood crate, instead of 25, is what you have just shown a photo of my friend Fragman.....A M41 type can that contained the corks, and small cloth black powder packets for the 24 practice grenades. This can of corks and powder charges went in the 25th space of the standard wooden grenade crate. Then the black powder charge and cork were supposed to be installed just before use at the training range. I have seen and handled just one of these cans before that was in a friends advanced pineapple collection. They are very rare to find. Although I do not remember now if the cannister I examined said M21 on it like the can you have shown. :tinysmile_angry_t:
Here is one more issue that I think may be partly answered by what you have shown......I have always thought that the yellow-brownish varnish that was used to seal the corks on the bottom or practice grenades, and that is seen all over the bottoms of some blue grenades is a post war procedure. I do not think the corks were sealed with varnish on practice grenades "during" WW2 (pre-Sept 1945). Although they could very well have been done like that in very late war (1945) period
Frank "Eodtek" is also helping look for the answer to this question of the varnish which I made a separate thread about and asked this about a month ago. No one yet has been able to answer this question.

Here are a couple threads that have talked about M21's and MkII practice if you or anyone else is interested. There are even more threads, and when I find them, I might add them here to have all of them in one place. In fact I might start a separate thread dedicated to this issue of the M21.
I already made a "M21 Grenades" thread showing my two examples, and then others make new threads about the same thing, then I will answer, then others will answer, and then there is info and posts all over the place in many different threads. It seems my thread or a another thread would have to be I think called a "sticky post or tagged" by a moderator for everyone to stay on track and have definitive info in just one place or thread??
