    One 'Patent' Pyro stove now brought back to life again! Two reasons for posting this one: first the general dearth of flame shots amongst the existing Pyro posts, and second this is the version with the conventional pump arrangement currently only covered by the Archivist5 2 photo test posting (https://classiccampstoves.com/threads/1102).

    Interesting to note the massive wear on the pump tube cap and the bar specification stamp still visible on one of the legs:

    The Pyro has same size burner as an Optimus 00 or Primus 210 and equivalent power output. But with the larger size tank it is really a more elegant equivalent to the Svea No.12. The unique and peculiar pressure release system is fully discussed elsewhere.

    I suspect that this conventional pump version is probably a more recent variant to the combined filler and pump form, but does anyone know whether this is in fact the case? or have any better ideas on dating other than simply pre-WW1?

    Wasn't happy with the flame. Replaced jet. What a difference!

    One of Pyro's claims was their self pressurisation auto lighting feature. This seems to work very effectively, probably due to the direct tank top placement of the spirit ring and burner unit. I'm not convinced the Pyro vent system makes any worthwhile difference to switching off though. But for lighting up it reliably reaches the point shown here at the moment the pre-heat methanol burns out:

    Then with very little extra (pumped) pressurisation:

    With a Buflam pan ring, which just happens to fit the wide flat-bar leg tops perfectly, I can see this becoming a popular and well used garage stove.

    I as very interested in SMolson's Pyro here.

    I am pleased that you have found a later version with a conventional pump arrangement.
    The more I see of these Pyro stoves the more I like them.
