    So whoever said there are no dumb questions hadn't met me!
    I have looked so much that I have convinced myself I really don't know the answer (and I have an aversion to setting myself on fire)
    I have this nice 111 and I want to know if it is kerosene or white gas and have just about decided I'm not sure as you can see the label part which would have easily solved this mystery has been removed much to my dismay.
    I do know I am being overly cautious to the point of inactivity So I'm reaching out to the fine folks here to let me know which fuel my new pet would consume
    Many thanks in advance and for all the great info I have got from you all so far Much Appreciated

    Hi @Sparks the Op.111 is a kerosene-fuelled stove and has four pipe connected to the top, vaporiser part of the burner.

    The Op.111b is a purely Gasoline/Coleman fuel stove and has two pipes connected to the top part of the burner:

    Optimus 111b burner.

    You appear to have an Op.111 = Kerosene burner, but count the tubes!

    Just to complicate things you have what appears to be either an Op.111/7 or Op. 111T. The T means triple fuel and with some modification can burn Kerosene, Coleman fuel, or Alcohol.

    I hope you realise that there should be an outer burner cap on your burner. It has a multitude of small hole from which the flamelets burn.

    Which 111 have I got?

    Optimus 111/7

    Best Regards,
    Kerophile.

    Thank you so much for the response I simply do not want to do something to cause an accident by using the wrong fuel! And I want to make sure to label it properly in case I'm not around and someone would make a potentially dangerous mistake

    I do have the outer burner cap neglected to attach photograph of it
    Now another question please what is the "rope" in the photo made of ? Fiberglass?

    To me - from looking at your two first pics - it looks like you have the air-restrictor in place - that can mean it is supposed to run on Meth/alcohol - with the correct jet in place?

    have a look here a bit down the page:

    You should have 2 caps. An inner and an outer cap.

    @Harder D. Soerensen - You are right, that burner is an 111T rigged to burn alcohol fuel. I guess that someone shifted to this burner and removed the fuel mention as it was not right after the modification. It looks like it was born as a regular 111 or 111B in early 1970's.

    Finally had time to clean and take apart
    As you all have surmised it does appear to have been modified in the past
    It looks like she will be an alcohol stove from now on!
    Thank you very much for your help E017F82C-CC33-436B-96A3-FED334B642AF.jpeg BF3EB6EE-5889-46C0-8CAE-AF7D7DAB4CC9.jpeg 369111FF-DA33-4405-837B-B42BCC23E93C.jpeg B516BFD3-5B9A-4541-AE3D-459916F93C7F.jpeg 016B7C5C-E21B-4A43-AC50-778E615E9DEE.jpeg E017F82C-CC33-436B-96A3-FED334B642AF.jpeg BF3EB6EE-5889-46C0-8CAE-AF7D7DAB4CC9.jpeg E017F82C-CC33-436B-96A3-FED334B642AF.jpeg

    @Sparks
    Always glad to help.
    Assuming your jet pricker is present and working - all you need to make it run on Kero/Coleman Fuel (White spirit) is to change your jet to this one:

    Optimus Spares Price List
    part # 2509
    And then remove the Air-restrictor tube.
