    Hi, here are some images of my latest acquisition. I am really pleased with it!

    This is an Optimus 155 stove. It is paraffin-powered and has two silent, regulated burners.

    The stove has just passed the "Tea Test", boiling kettles of water for me to make a cup of tea.

    The shots were taken with a hand-held camera, without flash, in a dark, untidy garage....not my best photos!

    It is an interesting stove, which I believe came off a boat.

    The pump is very long stroke and the knob locks in the store position using a bayonet type catch.

    The label is informative. You can see that they are claiming 2.4kW maximum output from each burner.

    Best Regards,
    Kerophile.

    George; she is lovely; but how can you tell if it is alcohol or kero?; have a lot of international students in my town and am looking at one; really not interested in an alcohol burner?
    thanks;
    Lou

    Hi Kerophile

    Nice stove. Looks to be in good condition - and it certainly burns well.

    The rail certainly suggests it was intended for a boat.

    One of the things I like about these photos is to show us that you are human after all - your garage is nicely messy! :D

    Hi Lou, this cooker was available as either kerosene or alcohol fuelled.
    My one is kerosene, using Optimus 207 regulated burners.
    The alcohol version is fitted with Optimus 209N regulated burners.

    According to this brochure:

    https://classiccampstoves.com/threads/9155

    The kerosene burners produce 3800 BTU and use 0.25 litres/h.

    The alcohol burners produce only 2480 BTU and use 0.33 litres/h.

    Hope this helps.
    Best Regards,
    Kerophile.

    Hi Lou, these stoves are well designed and fairly robust, and they can generally be fixed if not working.

    However, I would avoid any stove with evidence of excessive corrosion of the tank, frame or burners, or too much missing enamel finish.

    Check the piping, burners and tank for cracks, dents and deformation. If you see any evidence of significant damage, avoid.

    Check the regulated burners, and their operation, as these burners are no longer available and can be very expensive.

    However, repair kits are available at reasonable cost and providing the body of the burner is sound with no obvious leaks, pitting, or erosion/ corrosion they can be fixed.

    Good Luck if you decide to proceed.

    Best Regards,

    It seems pretty clean and is all stainless steel; can't see any corrosion or cracks and not many signs of use; will see if it stays with me :)

    G,,day kerophile.
    i have tried enlarging the photo of your kettles.
    but i still cant see the detail of what appears to be some sort of heat absorber on the bottom.
    any chance of a photo please , and maybe some information.
    thanks
    cheers

    Hi Kerry these are two versions of veteran Quick Boil copper kettles (one is chromium plated) intended for use on open flame stoves. The kettles are are tin-lined.

    Each kettle has a capacity of approx 3 pints or 1.5 litres.

    Their unique feature is a metal coil enclosed by a vented skirt, which surrounds the base of the kettle. This is claimed to act as a heat- exchanger, enhancing thermal efficiency.

    Here are some photos:

    The kettles seem to work well and do look good on a classic stove:

    I was much amused when the major camping goods suppliers re-discovered the benefits of heat-exchanger coils and baffles and introduced them to their Hi Tech cooking pots.

    Kerophile.

    should only need a inner and outer cap but it could well work with that cap anyway.
    I had one of those caps working ok on an msr dragonfly

    Hi Lou, no worries. The cooker looks to be in very good condition. Burner caps are 'consumable' items on these stoves and are replaced when necessary .
    You probably only need an inner and outer burner cap for the left hand burner, and a set of new seals and washers to fettle this stove.
    Nice acquisition.
    Best Regards,
    Kerophile.

    Hi Lou, some people start this hobby with simple stoves and then progress to the more challenging.
    You have now acquired a second lovely, challenging stove.

    In the photos of your new stove I can see black ball-headed knobs alongside each of the red/brown burner regulator knobs.

    In the second photo, taken from below, I can see two tubular items pointing in from the top of the picture, each one towards its own burner.

    You have QUICKLIGHTERS!

    Have a look at this post of a single sister of your model:

    https://classiccampstoves.com/threads/optimus-154w-154.6438/


    And here is the twin:

    https://classiccampstoves.com/threads/opti-155-with-pre-heaters.18555/

    If you look at this exploded diagram you will see what complicated little beasts these quicklighters are:

    https://classiccampstoves.com/threads/10189

    Of course you can still prime in the old-fashioned way with alcohol in the spirit-tray, as use of quicklighters takes an awful lot of tank pumping to get the pressure to atomise the fuel in these devices.


    Optimus did use pre-heaters on some of their 155/55 Marine, two-burner stoves. I have only used the device on Petromax/ Hipolito lanterns.

    These pre-heaters work from the main tank, and are paraffin-powered. However the quicklighter burner works on the principle of atomisation to produce a flammable aerosol, rather than on thermal vapourisation of the paraffin.

    The fuel tank has to be pumped to quite a high pressure (the tanks usually have a pressure gauge fitted) before the valve on the pre-heater is activated, and the exiting jet ignited.

    Once the main burner is heated sufficiently, the regulator valve is opened, the main burner ignited, and the pre-heater extinquished by closing the valve.

    I have studied the pre-heater jets and they are very fine, 4-5 thousands of an inch, I estimate, and need their own dedicated prickers to clean them.

    Looks to be a really interesting stove and fettle.

    Best Regards,
    George.

    OK did a temporary repair on the filler cap/pressure gauge; it was loose because the "O" ring /seal was dry and compressed into a groove so did the "redneck" thing and carefully took the seal out, wound some cotton twine behind it reversed it and and put it back in place; tightened it and pumped; :clap: yippiii; it is holding pressure; needle in the green!
    preheat as you told me, still with pressure :clap:
    1398642122-2014-04-27_17.45_preheating_155.jpg
    fire her up trying to keep kids and dogs away ;)
    1398642613-2014-04-27_17.53_blowing_and_going_155.jpg

    never could get the left side to do anything but big yellow flames + smoke; so guess I will need the parts you recommended :)
    now the threads on the filler cap/cover/gauge are 20 x 1,5 metric, so am needing a seal of that size, cause my redneck repair is a temp thing to get her going.....any ideas of metric seals?; round here we deal mostly in inches and fractions . again appreciate the help and kindness; and apologize for any hijack BUT am too ignorant to get photos posted on personal messages;
