I have had this Jewel stove for some years now. It is really a nice little stove. I got it cheap even if it is in excellent condition, because the original box is missing. I have tried to see if it can fit inside an old Høvik or Radius box , since I have a few of them , but the tank of this Jewel stove is slightly higher, and it don't fit in. I suspect that the windshield is not original either since it seems somewhat short. But I am not sure. It would not burn when I bought it ,and I found out that the nozzle was completely clogged and could not be prickled open. Luckily a shop here in town had lots of nozzle points in store ,and the tool needed to change it. So with a new nozzle point and pump leather it burned like a dream. I am not sure when this stove was made , but I should think it maybe was in the nineteen thirties. But I am not sure of this either. Mabye this stamp is an indicator ? This stove don't get to be used much unfortunately due to the lack of some sort of container for it.
