Arvid Böhlmark Orbis

Hello.
Got my hands on a Arvid Bøhlmark primus,i belive after searching ccs threads that it is the model ORBIS.There are no stamp on the tank or burner.The only stamp is on the filler cap,the NRV looked very different too what i have seen before.So i gave some oil over night,then tried too fire it up and it burned nicely.But its missing a flame spreader on the top.Does anyone have a picture of what it might look like.
Best regards

Wow that definitely does look to be an Arvid Böhlmark's Orbis. An astonishingly rare find. A one year only commercial offering - 1896. You may need to visit the Swedish National Museum of Science and Technology to see the example they have there. That may well be the only place you are going to see what the flame spreader should be like, assuming their exhibit still has its own original flame spreader!

 

Thank you for your reply.I belive it is a ORBIS too.I would love too make it burn perfectly,i will continue my search for a flame spreader.I was suprised that the stove had no leaks in nrv,filler cap or burner.It fired up perfectly,but missing a flame spreader.

 

Hello, a super find! Can we see a photo of the burner from the top?

Thanks

 

Here you go,hope this help,adding a photo of tank bottom

 

That’s a really uncommon design and we haven’t seen a flame plate for the Orbis. Also the other known example is missing it.

Probably a complex plate is required, similar concept to Svea 801 burner.

What an exciting find, with such rare stoves every additional discovery adds enormously to the knowledge base.

The tank bottom is superb, with those pronounced marks from the metal spinning process. And all the Bøhlmark hallmarks- heavy, attractive tank, beautifully decorated filler cap. A beautiful product if sadly not financially viable.

Good luck getting it running, action photos are eagerly awaited!

I'm wondering if this burner would have a "UFO" style top cap - looking at how the flame is rising centrally through the burner?

 

Not sure if this helps at all; but it is an enlargement of the burner on the only photo I can find of the Swedish Technical Museum's 'Orbis' stove:


And a possible way of attempting a beginning to working out what sort of flame spreader might work. This was an innovative starter experiment @threedots used on an similar age Alexandra stove;

 

Thanks i see the idea,i will try too work something out.
Thanks

 

I tried with a ordinary primus ufo,but the flames only went around because it too small.The pressure on the flame is okay,if i only could spread it someway.I will post pictures ad i go foreward
Thanks everyone.

 

I got this in box with two other stoves.Hirschorn AG model Hekla and Graezea but i started with the Orbis because i belived that to be the most rare one.
Thanks everyone

 

Neat old survivor. And if the experts are correct an astonishingly rare one (my knowledge of the very early stoves is limited to what is posted here).
