The only reference I can find for Jewel are Detroit USA manufactured stoves. Whether it comes from the same manufacturer or American I do not know. It looks similar to a Juwel 3, 6 tank style. Just won one in an auction. It has the older (before the 1896 change) non return valve at the bottom of the removable pump tube (small diameter with hex nut). Sorry pictures will follow once I get my camera sorted. Thanks in advance, John
IMO its Juwel if really described "Jewel" - could be after germans authorisation production more USA Juwel here https://classiccampstoves.com/threads/from-hunting.31290/page-17#post-387838
Hello @Robtz. When I first looked I thought it was a Juwel so it was on my hit list and when I received it, I was surprised that it was not a Juwel as we know them. It has brass pot trivet legs, the pump enters the tank into the side like say a modern Primus Nr:5, instead of entering on the bend where the tank top and side meet like the Juwel 6 has. Also the tank fuel cap is different. The burner is different as well. The only brand markings on it has a star * JEWEL PATENT *. @gieorgijewski Thanks for you link but unfortunately I cannot view it at the moment(computer problems). It is marked JEWEL instead of JUWEL so whether it is a JUWEL but changed for some reason I do not know. It has an anti oxidant oil applied to it at the moment and hopefully I may get some photos up tomorrow. John
This is the stove after a cleanup. The tank markings and an 'S' marked on the tank list are the only markings I am able to find on this stove. Does anyone know what the 'S' means? The burner has a jet that is not meant for it and is partially inserted. I had this stove running as it is and it burned well with that jet. I am hoping that the original jet thread is still good to take an original jet if I can find one but until I do get another, that jet will remain undisturbed. The NRV at the bottom of the pump tube is different to what I had originally thought the stove had. Further photos will follow. John
More photos to come of the bottom of the stove which has had a great deal of solder smeared over by someone in the past, as it has a crack in it. The soldering held up until I pumped more pressure into the tank to get the stove running at full blast. It then began to leak slowly so now I will have to fix the problem. The soldering may have covered up other identifying markings but I will have to remove the solder to see. John
@multi-cho This tapered threads nipple would be usable on the juwel burner? I think it is meant for burners with damaged nipple threads. Munstycke Nicola
Hello @multi-cho . Sorry about the late reply. I am very interested in your topics about the Juwel/Jewel stoves. I have not yet removed the nipple on my example to see why it is not seated properly and am reluctant to do so as it burns well as it is. I fear the original thread in the burner could be damaged. Looking at your example of what the original nipple looked like (square on the top and with a tapered thread). It looks very old (1890's?)and it looks like the tapered thread was a deliberate design at the time as a way to ensure gas tight sealing when the nipple was inserted.
