Ok, finally it's mine. After 8 years my friend gave this stove to me. He was trying to restore it but there are many problems because of war in Ukraine. Firstly this stove was mentioned here. I've got the stove about couple of weeks ago. Conditions was very bad, ruined as a fact. But the great project in restoration. The tanks was leaking, burners uncompleted, a lot of parts lost or broken. I did a lot of works to back the stove to life again. A lot of pics and results below. I believe this stove is a full copy of Swedish Radius No 12 (earlier version) and was produced about 1939-1340y. I don't know how exactly SRV gaskets and springs was look like and i did it like classic Radius style parts.
Every part have the number stamped on it as a style of an aircraft parts manufacturing. Parts sizes and threads are different than Swedish Radius-12 probably with according to new (for that time) USSR metric standards but a bit different than modern too. The halfs of a stoves is different (not only LH/RH ) and some parts from one cannot be mounted to another. Even the regulator handles of burners are different, as you can see small airplane in the one and bigger on another. Anyway i was very enjoyed to do the restorations works on this stove, it was so much and i'll not describe it here, just see the pics. And a result that i proud.
