Help to identify this wood burning military stove.........

Hello,

I'm trying to find some definitive information on this stove. I personally used one this past summer while camping in Sweden. I think I remember I was told that it is a Swedish Army stove. I've spent countless hours trying to find information, etc on this particular stove.
The 2 covers you see on the top are removed have allow for placing large pots inside to heat water/food. The oval top can also be removed and a griddle style top is placed on top for cooking as well.

Anyone have any info? Anyone ever seen one of these?

Thank you

Joe
