    Today I picked up this Optimus 111 from a local ad placed on FB Marketplace. The seller said it was a gift but was never used. I think it was used at least once due to the light carbon buildup underneath the burner. Also, there was burnt-on sticker residue on the burner cap (where I assume the “Tested” sticker once was in place).

    I gave it just about a 15 minute cleaning and other than the rust on the outside of the case, it appears to be in good condition. I oiled the pump assembly (it has an O-Ring instead of a leather cup) and the gasket on the filler cap seems in good shape.

    This is my first Optimus 111. I’ve read several threads on this forum and I’m really just curious what to call it. “Optimus 111T,” “Optimus International Hiker,” or just “Optimus 111???”

    From what I’ve read, it should run on white gas or kerosene using the same jet? There were no extra air restrictors included so I don’t believe I’ll try alcohol. I’ve got enough Trangia stoves for that.

    I’m getting ready to test fire it (with Coleman gas) and will report back later. Hopefully it will operate as easily as the 8R.

    I appreciate the help.

    First lighting and tea test worked perfect.

    Boil time for 1 cup of water was just shy of 4 minutes.

    @Andrew Johanson

    I’ll stick my neck out and say it’s an Optimus 111T that was marketed by Optimus, at least from the 1980s, variously as Optimus 111T “Hiker”, or just Optimus 111 “Hiker”.

    For example:

    “111 Hiker Triple Fuel”:
    https://classiccampstoves.com/threads/optimus-international-catalogue-uk.47879/

    111 “Triple Fuel - Hiker Stove” (1987):
    https://classiccampstoves.com/threads/optimus-“adventure-equipment”-price-list-1987.47647/

    “111 Hiker” (1993):
    https://classiccampstoves.com/threads/optimus-“adventure-equipment”-price-list-1987.47647/


    So, “Hiker” was a sales name attached to the Optimus 111T stove (where T stands for triple fuel), in my humble opinion, but @Staffan Rönn may be able to provide more knowledge and nuance on this subject,

    Cheers

    Tony

    You are much appreciated, @Tony Press ! In my earlier searches, I had read those posts previously and had not put it all together that “T” meant triple (fuel). Thank you for clearing that up for me. As such, I’ll just stick with Optimus 111T for my use/nomenclature. I am very happy to have this stove in my collection!

    +1 on 111T
    Great score for that price!
    It can run on Kero/Coleman Fuel with that jet (or a mix of both)
    If you get the jet for meth/Alcohol (larger Aperture) and an Air Restrictor - It’ll run fine on Meth/Alco as well.
    You’ll get the most power out of Kero though.
    Its very good for slow-cooking as it simmers quite well

    After I run through this current tank of Coleman fuel, I’ll try using kerosene.

    very nice, i'm in agreement and only add that at times Optimus referred to it as model 111T "Hiker" link , while i was looking your knob appears in '89 catalog (not earlier that i saw). myself i don't yet have year range for that embossed "International" case.

    I prefer kerosene with this stove for several reasons.
    The NRV is the main reason.

    @OMC , thank you for the info. I love viewing those old catalogues. The socket at the end of the knob is supposed to replace the small wrench in earlier models I suppose.

    @snwcmpr , could you please expand on your statement regarding the use of kerosene and the NRV?

    There is much to read here about the NRV, how it works, and what happens when/if it fails.
    I would suggest a little searching. I would only repeat the posts poorly, and with too little information if I tried here.

    I understand the concept and function of the NRV so I’m assuming you’d prefer less of a “boom" should it fail while using kerosene as opposed to white gas.

    My perception is that giving both old and new stoves names like "Hiker" (111), "Hunter" (8R), "Climber" (123R) etc. were an effort by marketing people to modernize the range and give it a more emotional appeal and attachment to potential customers. This seems to have happened during the first half of the 1980's, see for example:
    https://classiccampstoves.com/threads/optimus-stove-catalogue-mid-1980s.42490/
    This was also around the time when the 221 triple fuel burner was introduced in the 111.

    The "T" denomination (111T) must clearly be a short version of "triple fuel", but I have not yet seen any proof of Optimus in Sweden using this "T" denomination. It was, as far as I remember, always just "111 Hiker". "T" is something that was used in the UK subsidiary and possibly elsewhere.
