    Hikerduane sent me this stove last year or the year before, I don't really remember. Everything is a blur before October of 2013. All that matters is that he offered it to me and sent it. What a good friend!

    There's really not much to say about this stove other than see this post by Pinky: MSR Model #9. The link will take you to a wealth of information on the rare No. 9.

    This stove had a little trouble. The bottom of the burner, which has a small rounded nut had come off so I had to silbraze it back on in order for the burner to be attached to the stove cup. The fastener that goes into the bottom of the cup and into that nut is what holds things together.

    Other than that, being a 40 year old piece of hardware, I found that it performs very well, even after all these years.

    The pump and bottle are from an XGK that I also procured last year. They are both as close as I can get to the same vintage as the burner. I did a full restore on the pump and replaced every soft part for this small presentation. Pump still works excellently, although a bit old. If I did take it out, I would probably take along an extra set of Viton o-rings just for good measure.


    Here's a shot at the whole stove. That's all I have, but it's good enough for me. Thankfully, MSR's latest pump will work on their very first stove. Amazing.

    The sparker...

    View of the fiberboard bottom. It's not flame proof since some of the fiberboard has burned off in its previous life.

    So, this is interesting. There are O-rings inside of the the retainer. I suppose it was used as spares, but then, none of these o-rings are the right size for anything, so it may be just cushion or buffer of some type.

    The pimple is unusual to the No. 9. Not sure why it was designed in.

    That priming pad has got to be original to this stove. It looks it too!

    A side view of the burner removed from the cup. Notice how it is retained within the cup with the bolt. Later models have a small rod that runs horizontal through the bottom and the stove is twisted on. This design is much better and provides a simple way to dismantle the stove. I think MSR should have stuck with this design.

    The cotter pin as seen on the No. 9 and later models into at least the 80's and probably the nineties. I'm still guessing its purpose at being for priming fuel to drip down onto the priming pad. It doesn't hold anything and do anything else.

    A view into the burner with the jet down at the bottom. It's a bit different from later models.

    1403241609-xMSRNo9_012.jpg


    Here's the jet up a little closer after removal. It appears to have a screen on the inside of it to filter out the big pieces before they would ever get stuck in the jet.

    Here is the defining feature of the No. 9 - the scalloped burner bell, which is not completely scalloped but has flat and jagged edges. I guess my theory on the scalloped edge's purpose is to provide more thermal feedback to keep vaporizing fuel. There is more metal so it would provide more collected heat. I suppose it doesn't become necessary anymore with a looping vaporizer to take a direct exposure to the flames. MSR must have not found it necessary, so later versions like the Model G is not scalloped.

    1403241726-xMSRNo9_017.jpg


    One more little feature. The locking block has a hardened sealant or cushion on the pump retainer. I noticed that as I attached the stove to the pump.

    1403241744-xMSRNo9_018.jpg



    Here's the whole setup with the borrowed hardware. Looks like it all goes together anyway.

    1403241763-xMSRNo9_019.jpg


    Here we are starting the priming burn. There's no pressure behind that flame. The stove with a little fuel creates a flame like this. I applied a little pressure on it and it got quite exciting, but very fun!

    Very nice stove!

    For what it's worth... I just noticed recently that msr is selling a tshirt with the schematic of this revolutionary design.

    Nice Sam. Thank you for sharing.
    It is on my short list. One of those early MSR stoves (supposed 9A)was on eBay a few days ago, without the scalloped bell and a yellow pump.
    The 9 really does have some unique design features.

    The T-shirt may be available at a local retailer if you check the 'authorized' resellers search function.

    Good looking stove; good like flames, Sam.

    I actually won one of those Model 9 shirts when I submitted a photo of my MSR DragonFly stove in the snow, that and a hat. I wore my Model 9 shirt to the recent CASG where I got a couple chuckles.

    Just happened to be looking in the Stove Reference section for info on a RARE stove I just got. Sam, not too big a friend, after all, I did charge you for the stove, which promptly broke as you mentioned to me. If I'd played with it a little, it may have been turned into a parts stove by me, so very glad a handy person acquired it and kept it running. Who would have not only a great working 9, but a parts one too? :) Glad to see you are about. Take care. If HJ has one now, I don't have to find him one then, just Ken now.

    Congrats Sam!!!
    I know that one's been on your list for a while.

    And hats off to Duane for making it happen! :clap:


    Learned some new stuff from your post!
    As David Shouksmith said, every day's a school day on CCS!


    Is that one of those fuel bottles with all the fun graphics?
    Do you happen to know a ballpark estimate of when they were produced?
    I've seen a few of them floating around the internet, but they seem to be pretty rare.
    They look fun!


    Congrats again!

    Hey Pinky,

    Thanks! The fuel bottle is just a plain ol' MSR fuel bottle that I believe was out just before all the red bottles but after the SIGG fuel bottles. It is stamped MSR on the bottom and has MSR painted on the side (you can't see it in the pics). Not sure about that, just theorizing that to be the case.

    The label has the stove operation instructions on it. It is a bottle I borrowed from another stove that I will post in a while, which is an '83 or '81 XGK, I believe. I don't have it in front of me, but will give all the details in that post.

    Yeah! Thanks Duane! It's nice to have my very own No. 9.
