    I wasn’t looking for another 1/2-pint Parasene stove, but I had another project, an acetylene lamp, that the stove tin was perfect for, size-wise.

    I’ll get that out of the way first. The lamp has an outer tinned steel water container ...

    ... holed by rust.

    The water’s not pressurised and I was on the lookout for a liner, but the Parasene tin would have served.

    In the event, I killed the rust and sealed the pin-holes, so the Parasene tin was not needed and the lamp project was successfully concluded.

    So, back to the Parasene.

    I’ve added the Parasene logo and though nothing prior to that indicated that the tin was sold with the stove, it’s a perfect fit and deserves the logo I think.

    My other 1/2-pint Parasene has a conventional (though 2-pinter stove-sized) silent burner.

    The Zora burner is an oddity, resembling a silent burner in terms of its vapourising tubes and mixing chamber arrangement, but it’s a roarer burner with a flame plate.

    The stove proclaims it’s Entirely British Made.

    It’s a fixed-leg stove obviously but a collapsible type was marketed, such as Ben’s fine example.

    The spanner/wrench that seems always to be of the Rowe brand with these Parasenes.

    Trivet.

    Playing around with silent burner caps to offer a ‘silent’ option.

    Primus No.4 inner and outer caps both sit on top of the mixing chamber. Unsuitable. The jet on these burners has a 0.32mm jet orifice, which would overpower the No.4 caps anyway (0.23mm jet compatible).

    A 2-pinter silent burner stove’s caps are a fit, sort of.

    Best fit maybe is a 100-series stove’s converter cap, this from a Petromax 100.

    To get it not to slip around on the burner I’d to insert a temporary riser tube liner sleeve.

    Therein lies a problem with fuelling, restricting the air available for combustion.

    Obviously.

    A better arrangement to secure the cap on the burner without restricing the air, or a jet swap for one of 0.23mm would resolve that. Maybe some other time.

    John, I love a Zora burner me. An excellent example. Please keep going with the research.

    Success with a 2-pinter stove silent burner inner and outer cap Si.

    It requires a stubby piece of brass tube ...

    Photo sequence shows how it works.

    There’s just enough clearance to accommodate a kettle.

    More so with the trivet of course.

    Combustion is good and vapourisation is maintained.

    Thanks John. It's a nice stove, an unusual burner and an interesting conversion. :thumbup:
