Good to see that you have got one of those few Finnish made stoves also! This miniature anti tank mine (Mini Tellu in Finnish ) looking stove is very compact. I have had one for some years. Would be interesting to know if they got a license from Koma Nyköpingsverken KOMA or do they just copied it. On stamp they mention "Patents", but I am not sure if that relates to that stove or generally that "ALU" company had some patents on that time.
Thanks for the comments, Father-in-law gave this stove as a birthday present. He had acquired it in the early 60's. Observations: Needs decent preheating, No flame control, Wind sensitive - needs wind shield, Heavy (compared to catfood can stoves), Maintenance - prickering time to time, Boil Time - moderate as long as it is calm, No sooting. I decided not to polish it - let the patina be.

@Kall399 If you start a thread with some pictures of the problem, somebody might be able to advise a repair method?
Lift the steel lid in the middle of the stove and pour sprit. The material inside absorbs liquid quite a lot.
