    Hi, I'm new to the forum and am trying to figure out what stove I have. I thought it was GK and have a GK instruction booklet that came with it but reading up in it makes me think it a 9-MF as I also have a 2 page instruction sheet dated May 1976 for MSR MULTIFUEL STOVE.

    I was stationed at the army hospital on Oahu and bought the stove for a backpacking trip to the Napalii Coast of Kauai. I'm fairly certain that I acquired the stove in 1976. I was transferred to Arizona in 1977. From what I'm reading the GK came out in 1978. To confound matters there was a tag on the stove that said Model 9. I have everything that came with the stove except for the aluminum cup. The 1 liter red Sigg bottle has no decals and a plastic cap.

    Hi @waltie -

    Thanks for your service.

    Some.qiestions:
    Is burner smooth or scalloped?
    Does fuel pipe have a aluminum rod or a cable inside?
    Does fuel pipe go over burner?
    Where is the 'model 9' nomenclature? On stove or pump?

    Scott

    1st .. Welcome to CCS.

    Is the generator tube flat across the top, or round.

    You can look in the Gallery for stove images that look like yours.

    After the MF (Multi Fuel) there was a DF (Dual Fuel), then the "G" & "GK" (Field maintainable) stoves. The G & GK had a removable cable in the fuel line.

    Welcome.
    Like others eventually i may like to see it but i feel as though
    >>> you've answered your own question?
    I'd say, with 2 caveats, your stove is an MF.

    Per your
    >>>"...a 2 page instruction sheet dated May 1976 for MSR MULTIFUEL STOVE."
    >>>"...I'm fairly certain that I acquired the stove in 1976
    [GK not out yet]. I was transferred to Arizona in 1977."

    A complete MF that I have came with the model 9 tag, you're right to question it but that early No.9 warning tag was sent out with stoves long after no.9 model ended.

    caveat #1: I would have thought a stove packed up with May 76 instructions would have had a big "MF" tag on bottom.. now that i mention it, do you happen to recall big MF tag? (a tag that might soon fall off w/use). Or is there maybe a rectangle on bottom from residual adhesive where the tag was?
    caveat #2: GK instructions... it is currently a mystery where they came from but if you have 76 & 77 dates correct above, as far as I know you could not have acquired GK instructions before 77.
    thx omc
    PS ...an MF purchased in '76 :-k , and a yellow pump then...
    "I do find that the Yellow pump w/pins was offered by Jul. 75 until early 77.
    (and that range might expand a little: earlier / later).
    " , source, me.

    Wow, thanks for all of the reply's! first of all I'm computer challenged and have difficulty with attachments unless I can drag and drop them. Nowhere on the pump does it say model 9. Just that warning tag. Some kind of a rod inside the tube but it doesn't look removable. Burner is not scalloped. Black plastic base held on with 2 rivets.-Generator is rounded. Yellow pump has a brass push pin where the fuel tube plugs in.
    Carpal tunnel is kicking my butt so I will sign off for tonight and will try and look at the gallery pictures. Thanks again.

    You can drag and drop images to the text box of a reply. Then you choose thumbnail or full image.
    Rod in fuel line and rounded generator sounds contradictory.

    Did you look at the Gallery?

    As I said earlier I'm electronically challenged. This is actually the first time I've used my phone to comment to a website. I'm getting ready to list my old MSR stove on eBay and thought I would try and get some pictures of the stove on the site. The stove will be listed at 4PM this coming Sunday. IMG_20191009_125151.jpg

    The cable in the fuel line is removable and thus it is a GK. The G & GK were introduced as the Field Maintainable Stove. That cable can be pulled out to clean the fuel line. The rod, if it was there would have a flat end.
    I hope that helps.

    I was there around then, I left Oahu the year before you bought the stove. I spent 75 in Long Beach.

    Snocmpr, actually the last time the stove was used was on an ice climb on a frozen waterfall in the Blue Ridge mountains in Virginia. I think it was around 1985 or so. Have not thought about that in a long time!

    I hope it helped you melt a lot of snow.

    I had a reply on my email account from OMC. He suggested that I try to pull on the rod with pliers so I did. It turns out what I thought was a rod was a swaged on fitting to a stainless steel cable. Does this confirm an early GK?

    re "I had a reply on my email account from OMC."
    That's interesting.
    Thanks again for posting all this :thumbup::thumbup:.

    So it does have a cable in fuel line (a feature that came about later than mid 76)....

    Now, I'm not sure what to make of the items you have shared with us.

    Re early GK, yours is almost a match to Sam's early GK
    except, yours has:
    earlier jets (pretty sure, if I got that right) and, seems to me,
    earlier bakelite base.
    So I'm not certain it's an early GK (the only thing in-between MF & GK is a model DF?)

    Given the cable, i will leave it at: stove/burner is not an as original May 76 (or earlier) model MF.

    Pieces of yours that match up with a May 76 (or earlier) MF:
    yellow pump w/pins
    short catch arm
    early bakelite base
    early jet
    "MF" instructions and that you made a purchase in 76
    ==========================

    My comment re "early bakelite base" has not been entirely vetted either.
    Where I'm coming from with that is, the base of yours and Sam's early GK differ:
    The bottom paper labels aside (which most fell off), re just the bakelite bases:
    > yours, early, is simply:
    a larger MSR logo
    SEATTLE USA

    > a later/last version (Sam's early model X-GK for example):
    a smaller MSR logo
    SEATTLE WA USA
    U.S. PAT. #'S
    3,900,281 / 3,828,278
    & FOREIGN
    PATS.

    I'm needed elsewhere, sorry I can't give this more attention
    catch you later thx omc

    Once again, thanks for the input. I really can't be sure of when I bought the stove other than no later than spring of 77 and am fairly sure it was in 1976. I just can't recall when we went on the backpacking trip to Kauai but also recall a similar trip to Maui where we camped at Seven Pools out by Hana. Considering my getting transferred to Arizona in the summer of 77 I don't believe I would have had the time and or opportunity to make 2 trips in 77 prior to the transfer. Waltie

    Normally one would only pull the cable out. What do you mean by a 'swaged on fitting'?

    A swaged fitting is an attachment to a cable that is machine compressed to squeeze it on to the cable. When I looked at the end of the cable protruding from the fuel arm all I saw was a solid piece of steel. When I tugged on it to remove it I saw that it was attached to the cable. I used to do a lot of sailing. There were a great many swaged fittings on the cables that held up the mast and on the lifeline rigging.

    Any thoughts on what this is worth?

    The cable should not have been attached to a swaged fitting.
    Can you post a photo?

    @waltie ,

    Looks to me as if you have two different sets of instructions. One is for the G & GK, and the other is for the MF. These are totally different stoves. Yours is a GK. I have quite a few of them, and they are good stoves, if maintained properly.

    Looking at it again through a magnifying glass (my eyes are 17 days shy of 70!) and it now appears to be a spot weld on the end of the cable to keep the wires from unraveling. I'll try with the pictures but don't know if the detail will be by any good.

    Thanks for the verification. From all that I've read on this site I was pretty sure it is the GK. I'm fairly certain that the MF instructions came with the stove and I really don't know of any other way I could have acquired them. As an aside it also came with a wire tag on it for a model 9. All in all it was rather confusing. I'm aging out and hate the thought of this winding up in an estate sale or even worse, a landfill.
