    Saw this ERZET 640 on a German “Classifieds”. Have never seen it before, but the quite simple/rudimentary design made me buy it since the price was fair. It even came posted with 1/2 tank filled with smelly gasoline.

    The burner bell holds a loose inner ring and two top plates, which moves freely. Spares hold an extra top plate, filler gasket, some graphite sealing and an additional jet. The regulator moves firmly but free.

    Figured it must be tight since no leakage was seen during shipment. I then did a quick inspection of pricker and the SRV, put some new fuel in it, and fired it up. It just worked after (a bit of heat under the tank) in a strong steady flame with a nice roar. Actually it produces quite a lot of heat!
    Kettle test went fine - no soot and fast to make a boil.

    The stove was made by a German tin toy company HANS RUFF from ZIRNDORF (HRZ) which existed 1928-75.
    I actually sort of like the simpleness/roughness of the design.
    Cheers.

    I think I know what you mean, Harder, maybe the square-cut lines of the box but the tank is beautifully contstructed.

    Actually, the seller’s photos you showed me didn’t do it justice and your photos reveal the quality of the box construction too.

    I wonder if the double flame spreaders were intended, or if it’s just a place to stow a spare one? If so, it creates a stylish flame pattern as Kerophile has said.

    I like that! You also have one of those little kettle's I covet! You'd better make that "never ever sell shelf" longer! lol

    Nice catch. I'm trying to limit myself to 96's, stray once in awhile.

    Nice small stove! :thumbup:

    I would guess that one extra flame spreader is for spare.

    @MrAlexxx - That "never-ever shelf" shelf should be longer - I new it from the beginning :roll:

    My guess is that there should be two x burner plates mounted - at least judging by the pics of this little odd stove, which I can find on some of the Japanese collectors pages (They can go wild!).
    Have fired it up a couple of times and learned two things: 1: Because of the size of the burner bell - a thorough pre-heat is nescessary and 2: It starts better with a couple of seconds of lighter flame on the tank to make a bit of pressure. Once started - it runs strong and stable with a great sound 8].
    For some reason the firm clip mount in the box turns freely with the stove - as if it is prepared for uneven places where the tank can be placed in another angle than the box.

    @fyrwokr I wish Coleman 520/M1950 were easier to get around here where I live ;-)

    Congrats on a real gem you have there.
    I get that it is small, before it settles onto a shelf... re size? a pic of it aside, say, an 8R will provide scale or maybe measurements of it closed?

    I post re your: "...judging by the pics of this little odd stove, which I can find on some of the Japanese collectors pages"
    -or- where else right here on CCS, like new erzet 640 w/instructions and spares. Credit to motorcycle stovie PC-15 :thumbup::thumbup::thumbup:.
    thx omc

    Thanks @OMC
    I didn’t see that old post - nice new sample he got there.

    Mine will never end as a shelf Queen. Might shine it a bit since it runs stable and hot, and then use it for camp-/hiking trips.
    (Maybe as a trade object for a Phoebus 725 or a Coleman M1950).

    Will post it beside my 8R later tonight.
