    Here is a Juwel No. 21 that I picked up in Shanghai. It has Chinese inscriptions, in old Chinese script, but no other languages except for the word "Juwel" and "21".

    It did not have a flame ring. The one above is generic.

    With the steel windshield that came with the stove.

    "Juwel Juwel Germany" Note the casting blob on the top of one of the Juwels.

    I have been told that the inscription in old Chinese characters says something along the lines of:
    "[The company] is modest and reliable" and "the stove for automobile use" or "transportable" (my translator was not sure of the last bit...).

    "Made in Germany".

    "GB" and crossed swords.

    The travel cap screws on to the end of the pump rod (and leaves the rod thread exposed when not attached (see below)).

    The pressure release screw is from something else, with Chinese writing on one side and "SIN.HSIN" on the other.

    The riser for the small burner.

    Note also the relatively large priming bowl.

    It was straight forward to get going, but there are a few things to note:

    Lots of asbestos-looking washers.

    The NRV was shorter than a standard Primus-like NRV (Juwel NRV is at the bottom).

    The NRV is also unusual: It actually is made to be taken apart with a screwdriver.

    Washers etc from The Fettle Box.

    Note the thread on the end of the short pump rod where the travel cap screw on.

    The pump tube diameter is the same as a Primus No. 1 or 5.

    As it was found.

    Up and running (it has a 0.32mm jet - original):

    Quite a nice little stove really, and different from the other Juwel No. 21s in the Reference Gallery.


    Cheers

    Tony, that is a great presentation of an unusual stove.

    The name 'Juwel' of course is well known, but the stove is very quirky!

    Quirky indeed! That's why I couldn't walk away and leave it there. The fellow I bought it off knew it was old because of the old Chinese script, and wanted a solid (but fair) price. I was happy to settle without a lot of haggling.

    Have you ever seen an NRV like that? I haven't.

    Cheers

    Tony

    Tony, you are right. That non-return valve is of a different design to normal and looks to be well made.
    The solid screw-in bottom of the valve is a great idea.

    Hi, yes I have seen and reported one of those Juwel NRVs before (in Feb 2008)

    @kerophile

    Thanks for that. Is this design unique to Juwel and/or other Gustav Barthel products, I wonder?

    Cheers
