Unknown Mine ID Help!

Unknown Mine ?

This was found in Latvia. It weighs between 8-10 pounds and is 72-75mm in diameter. The base unscrews and the interior is smooth metal. The top has a small screw hole where a fuzing system could have been fixed but it is not in the center, it is pushed off more toward the edge.
History of the place: They have a tremendous amount of both German and Russian Ordnance from both world wars. The construction pushes me towards WW1 and the metallurgy is way more advanced than anything the Russians were putting out at the time. If you have seen this or know what it is, please let me know.

It reminds me of a Granatwerfer 16

I'm afraid it will remain unknown:

But is good to know that there is a place.

I do not know what this is, but I think it is either Russian or made by another former Soviet bloc country. In the link provided by stecol, there is a picture of a disassembled example. In that picture there is a fuze coupler that looks identical to a common Russian type seen here: http://www.lexpev.nl/fuzesandigniters/ussr/md5detonator.html It looks like the detonator tube was removed from the example in that mine, or it could be a different model, but the resemblance is striking. Also, the striker pin in the photo looks to be the same construction and appearance as what I have seen in Russian fuzes such as the MUV. (I do not have a good picture to share for comparison.)

I think it is from post-WW2, based on the good quality of workmanship and the very good condition.

All this is far from conclusive, but hopefully it points you in the right direction and gets you closer to an answer. I am curious and I look forward to seeing it identified. Whatever it is, I think it must be very rare!
