Identification assistance

[US-Subs]

After being shown a round in relic condition yesterday, I dug this photo out of my archive. I took this photo in a bunker in former East Germany about 10-12 years ago. Diameter is 82mm. Can anyone tell me the country of origin, the type by function and the purpose of the protrusions on the lower portion of the body? They are not rocket nozzles. Thanks, JO

I was told (by Joop) some time ago that it is an illumination mortar. The three protrusions at the base of the body are pyrotechnic fuzes, ignited upon firing. Each pyrotechnic fuze has a different burning time, equal to a traveled distance before expulsion. A small protective cap is screwed off the protrusion, opening the flamehole of choice to the fuze. The other two caps stay in place
