    Standard Primus No 5 that I was trying to leave with the patina intact but had too much overspray from painting the legs and had to polish it a bit. I note the pump knob is two parts (three if you count the rubber washer). The stove runs exceptionally well. Stamping is U 31. A solid performing stove.

    The photo below is of it burning and I clipped it from a video.

    The two part pump knob is shown below:

    Is that pump plated?

    Some of the Aladdin stoves/heaters came with a pump like that.

    Actually, it is. I had a look at the Primus stoves around the thirties including one of yours and I was wondering about this pump as it seemed odd. Good sturdy one, but maybe not original. I do have another Primus to do up so I’ll see what is on it.

    The outer part of the pump knob is meant to be a travel cap for whatever model of stove it was designed for (not a 1930 No. 5).

    Thanks Arch, Makes sense, I'll be working on getting the right pump and getting the balance of the stove that the pump belongs to. Tony has already given me a clue that I'll check into. My travel stoves have larger more dedicated caps so this is a first for me.

    Did I say Aladdin? I should have said Companion.

    Here is the pump off a Companion stove/heater showing the removable travel cap and knurling similar to yours:

    I’m not 100% sure it’s from that stove though...

    Cheers

    Hey Tony I agree that looks like it. Thanks for the pictures and info.

    However, this information

    suggests and sensibly so, that it probably doubled for a travel type stove. Now I'm thinking Burmos, some Primus or similar, but the ones I've got don't have the removable cap from the pump end. They have a separate cap. In fact I bought some recently from England.

    I recollect reading about it somewhere though. Did any Companion stoves need a travel cap? I can't recollect any with removable legs etc.

    PS The flame spreader under the burner cap is actually a Companion - Svea one so sort of gels.

    Regards

    Hipolito and other stoves also have this kind of travel cap, often on smaller bore pumps.

    I’ve got a plated Optimus 1S with the travel cap on the pump end, and I think I’ve got another Companion like that, too.

    I must turn the shed over and look.


    Cheers

    1930 was the first year of the "stepped" lower leg design, which Primus retained until 1963/4.
