    Hi, I have recently purchased a Comet No.1 kerosene stove. It is missing the flame spreader and the silencer.
    Does anyone have an idea of where I
    could find parts for it?

    Hello, a nice find, but unfortunately parts are impossible to find.

    The only option is to print them out starting from a 3d model… but you need someone to give you exact measurements of the parts.

    I wish you good luck!

    Thanks Nicola, Your help is greatly appreciated. I will use online images along with the measurements of where the parts go on the burner to get the parts printed.

    @yz125j you’re welcome. I don’t remember a photo of the inner cap, maybe someone could share it… but owners of comet 1 are very little :)

    I have the earlier version of Comet 1, with a different burner, otherwise I would have given you some measurements myself.

    Thanks again Nicola. Yes it would make the task at hand much easier if the dimensions were readily available.
    Your help is very encouraging.

    Hi Pete ( Kerophile ),
    I noticed that your stove is very similar to mine. You were lucky enough to get the flame spreader with it. I looked at the diagram that you included in your photos and realized that what I thought was the silencer for this model is actually the flame spreader. There is no silencer. I translated the word in Swedish for that part and it translates to flame spreader in English. Thank you so much for including that.
    Nicola commented that it would be good for me to have the dimensions of the spreader.
    Pete, would you be able to send the dimensions of your spreader?

    Your comet no:1 is the same product as the image introduced by Mr. optipri in the past. I think the comet no:1 I saw comes in 4 styles.
    Anyway, based on the two styles available in Korea, the silence cap is 36-37mm in outer diameter and 21-22mm in height, and the inner cap is 26mm in outer diameter and 9mm in height.
    Mr. optipri's vertical holes are not easy to make. I think it would be easy to make it with a regular silent cap like I attached.

    @multi-cho Interesting that you used an inner cap, it seems these stoves did not use one originally?

    @Blackdog Well, two out of the four styles I saw were the same type, and Carlsson's and the patent record were different styles... I can't see the exact data, but the dome-shaped head tube method operated normally using the inner cap.

    Including the main text and my disclosure, there are three styles.

    @multi-cho Hello! Nice to hear you!

    This is my Comet 1, my guess is first type pre-1912. On this version the pump valve is accessible from filler cap like on Moha stoves:

    I will add it to the gallery soon!

    @multi-cho I was thinking of the type pictured in this thread, neither the photos nor the catalogue images show an inner cap.

    hello friend!
    As far as I remember, this is the first time I've seen the same model other than Carlsson's data.
    That's really cool! exorbitant!

    @Blackdog ,@Nicola Francesco Elia

    After seeing your post, I called the member who owned two comet no:1 that night.
    I don't have any data, but try testing in both cases.
    I immediately received a call that night from a city in Korea called Jinju.
    You can do it without an inner cap!
    After playing two videos, there were no problems with operation.
    If you put the inner cap on, it feels much quieter, but if you don't put the cap on, it makes a very harsh sound.
    to your question
    For the first time, I was able to conclude that there was no need for an inner cap. For a long time we naturally assumed it existed.

    So the three versions are
    Everyone believes that inner caps are not necessar

    Thank you so much for that @multi-cho.

    The No.1 I am restoring is missing the original cap with slits, like other people's. I intend to try and make a replica in the long term, but it is interesting to see the stove will run with your Korean silent cap with and without inner caps.

    Is the inner cap in your pictures a product which is currently still available?

    Thanks for the reply, I don't have any products for sale.

    Thanks for confirming, it suggests the Comet No.1 isn't too critical in terms of its burner cap.
