    I'm not sure if this stove is a DF or an early GK. I couldn't figure it out after reading the thread here. What information do I need to make a DF decision?

    Well.
    If not a cobbled together frankie...

    The flat top and the "field maintainable" cable do show this stove to be a transition version.
    A nice item for the collection.

    @mojo,
    Congrats. Good question. As you have found (or not found), going with the details available today you could probably post it as "DF or GK" (late DF or early GK) read on.
    That rare combination could be / should be all original (not a hunch or guess btw).
    When MSR packaged that stove new it had it's MSR model designation not " transition version. "
    It has short catch arm, early bakelite base and came with one jet "wide top", unmarked. Under jet will be: surge damper cone, sintered brass

    You did not get pump, or any paper or packaging?

    *Minus original packaging some MSR 9_ / XGK models can be difficult to determine. Open questions remain.
    What I see looks to be an early GK. thanks
    =================

    *Open questions remain. As far as I know the following have not yet been confirmed:
    the last MF
    the first DF
    the last DF
    the first GK (i expect in future yours will prove to be a match to the earliest GK version)

    i'm less familiar w/WG only models but iirc other open questions are:
    the first 9A
    the last 9A
    the first G

    Mike Ridout was known to repair stoves.
    He was even known to make stoves.

    He was the face of msr in those days.
    It is entirely possible a transition stove came out of that customer service window that locals knew so well.

    In other words, cobbled together.

    He had an XGK running on tequila to cook a meal when all available fuels were just that .. tequila. I knew the man, he knew me by name.

    Thank you for your kindness. Thanks for the photos and information. I have two of this model. I bought both on ebay. One with GK instructions. Detailed photos of MF, DF and GK will be uploaded soon.
    Thank you ♪

    I think the leftmost one is an early MF. The two on the right are DFs or early GKs. They are the same but one was purchased as DF. But there is no proof.

    Wow! Tequila is usually about 80 proof, or 40% alcohol. I didn't realize that would burn. Probably better use for it than drinking, certainly. :)

    He was a wizard with XGK. He said that as an extreme statement of the possibility that the stove could perform. I believe it was a party 'need' situation.
    Alcohol is not an approved fuel for that line of stoves.

    Do you think he could have been cheating a bit? I'm not necessarily persuaded 40 proof anything will burn in a stove. I mean, maybe. I'd think a bit higher test would be required, particularly with a gasoline metering jet. Bacardi 151, now that would probably run after a fashion.

    Somebody needs to make a test!

    @mojo,
    nice lineup.
    you definitely peaked my interest.

    I know for myself a series of Q&A will shed much more light on these.
    If I may.

    Q1 Do all 6 have early bakelite base? (MSR mtn logo only, no embossed pat # s).

    Q2 Is there only one with paper model label in tact?

    Q3 Does the one with "MF" label (call it your MF-3 ?), does it have "...hole in helix..." ?
    If you peek under the jet do you see a hole?
    as shown here
    IMG_7491.JPG IMG_6017cut.JPG

    [[[[ @hikerduane , re your Unfired MSR MF w/label ... you can again be part of the solution :thumbup: and put on the hero hat, (still) an open question for key MF detail:
    under the jet, a peek at the helix threaded rod will confirm if it is solid or hollow?
    ]]]]

    Q4 mojo, depending on answer to Q3, going to the right your MF-4, DF-1 & DF - 2, with a peak under the jet do you see the "...hole in helix..." ?

    thank you, my hobby time is limited, but i will follow up.
    PS mojo you have seen this but for other readers and future ref., here are addl recent details re MF model link

    ==============

    btw DF or GK is the question. This is a topic already with ample conflicted accounts and inaccuracies.

    mojo's stove has a combination of parts inline with MSR DF & GK mass-production. No reason to insert confusion
    suggesting otherwise ( doubling down on " transition version. ").
    In all likelihood it is all-original and "When MSR packaged that stove new it had it's MSR model designation"
    DF or GK? is the question... it's good question, an open question...
    What I see looks to be an early GK.

    @OMC

    A1.These are all bakelite bases.
    A2.This MF is the only paper label. All without PAT numbers. Mark only.
    A3.Yes.
    A4.DF (GK?) are both brass filters.

    I can't speak English, so I use Google's translation software.
    Do these answers get you through?

    @mojo re your " i can't speak English"
    FYI my english is terrible/not "proper"

    you have been GREAT :thumbup::thumbup:, no worries. I am sure that is what all fellow stovies here would say as well.
    prompt answers and WELL DONE

    this is excellent !!
    [[ A1.These are all bakelite bases. ... All without PAT numbers. [MSR logo only] Mark only. ]] got it, VERY good.
    thank you

    fyi helix "...hole in helix..." this is the MSR term found on MF instructions.

    So,
    Q5 for your MF-1 & MF-2, with a peak under the jet do you see the "...hole in helix..." ?


    if they are still handy, others may have follow up questions. i probably should ask more about MF-4
    (wondering if it looks to be a match to the last ver MF)

    trying to be accurate, words matter, terms matter.
    re mojo's example in OP, i could rephrase my comment just slightly:
    What I see looks to be a match to an early GK.
    Caveat: confirming late/last DF would shed new light on this.

    for myself i am needed elsewhere and will check back as time allows (might get off early today).
    thanks again

    I just know what he said. He used tequila in an XGK to cook chili. He was bragging. So, obviously not an easy feat.

    @mojo should i guess your DF-1 is the "... one was purchased as DF." ?

    Seller presented as DF is a valid indicator. My thought goes to: Was there any reason to doubt him. It would remain as an indicator that it's a DF... short of proof, i agree.

    Grasping at straws:
    Considering there is very little confirmed for the DF (one labeled DF posted w/zero details). I then move onto some wishful thinking:
    Seller, if asked "Why do you say it is a DF?"
    He might answer that he bought it new (as DF) or say it used to have "DF" label on bottom?

    Hi,Late post.sorry.
    I checked the MF-1
    no hole.

    Is this photo correct? If I'm wrong, which part should I take a picture of?
    Please tell me.

    MF-2
    The jet is strongly tightened and cannot be removed.

    MF-3 with label
    I posted it before. It has a hole.

    Thank you.

    I think OMC probably numbered them after seeing the photo I posted. I know it's not numbered. Sorry if my words are hard to understand.
