Unknown object to ID, please

[Yodamaster]

Hello everyone,
yesterday, I received from a brother in arms, a request for the identification of an unidentified object. I hope someone here can help us with a correct identification.

Location of discovery: an Estonian garden

Length : 21,3 cm
Diam : 3,2 cm
Weight : 366 grms

Explosive : tested with Expray, 1 group, TNT
Metal of body : steel

The two grooves (base of the head and 1.2 cm from the base) are apparently identical and have a width of 0.2 cm.

More details will be impossible to obtain, the object having already been transformed into light and heat (destroyed for those who do not understand the hint!)

See the attached pictures. Again, I very much hope someone can help us identify this object. Personally, I would like to obtain a document reference concerning the object.

Thanks to all

No help whatsoever with a positive ID, but going by the thin casing and rounded tip my guess would be something akin to a bangalore torpedo,...but for the size....
Or perhaps a civillian mining/demolition charge for limited objectives.

pzgr40/42, when I saw the first picture, I had the same idea, a bang torp head, but then I received the dimensions and...

Thanks for answer

Does anyone have another idea, perhaps ?

If you don't limit your imagination by geography - it looks a lot like the body - minus tail, of the long Japanese submunition, a variation/cross between the German incendiary tail and a stretched German/Japanese HEAT type head. Size is pretty close as well. A lot of designs appear shared/copied from that period between Japan, Germany and Russia - perhaps?

Yoda,
Did you search in family of central burster (HE gaine beneath a fuze) ?

Here is the best photo I have at work. Second row down, left side.

It was my second idea, MinenAZ16, but I couldn't find anything similar. In addition, there is no system for attaching the booster to the fuze, no screws, crimping marks,...

Do you mean this one, US-Subs ?

Something like this, Minenaz ?
Badly, I have no dimensions in my docs !

Yes maybe something like this but so many possibilities...

 

[Yodamaster]

Well, well, well, the adventure goes on !
Same team, a few days later, same garden, the owner finds a second piece. He remembers that the two pieces were one piece but he only remembers that now.
Here the pictures of this second piece.

After looking in different sources, it seems that this part would be the booster assembly of a Russian marine mine, MKB. Could someone confirm and if possible provide the technical doc of this mine? Thanks

You have MKB mine in "Q-35-2-2" Russian Naval Mine section. Not sure about the US designation MKB, could be only KB (M added for "Mine" "Мина КБ")
Diagrams in my doc are not precise enough.
If you have time you can also try with this nice website : https://allmines.net/catalog/russia/mines/

Where can I find this book Q-35-2-2 ?

Hi Yoda,

Hello everyone,
the search for identification of this object resulted in a surprising and, hopefully, positive discovery.
We had gone on the path of a booster assembly from the Russian KB Navy mine.
My friend received from one of his sources a drawing much more similar to the second piece found. It would be a booster assembly of a Russian navy mine but of the M-26 and not KB.

Below is the drawing in question.

Could someone confirm this and, possibly, provide technical documentation and/or photos, which are more reliable than a drawing. I think this mine must be in teaching rooms around the world. Some photos identifying this booster assembly with certainty would be really welcome.


We are left with one question: what was this f****** piece doing in a garden ?

No luck the device is not visible on these photos

I know, Minenaz, I already watched them !

Hallo @Yodamaster,
if it was not for the measurements you posted, the item conforms exactly to the WW1 Mauser 90mm trenchmortar HE-round, with the baseplate and its fuzing-system missing. See the attached drawing from Berlot.

Eureka, my friend found the proof.
The part found is indeed the booster assembly of the Russian mine M-26.
He found a didactic one in a classroom and was able to check the location of his piece in his place.


Thank you all for the help provided.
