Here's the one I have (it's in the stove gallery). It has the integral lighter tube that coils around the interior of the spirit cup and snakes...
The burner on mine (stove must be pre-1920) is the later one (though the larger version - there were two sizes for the cap). I think 1920 is the...
Beautiful work, Nicola: are the legs heavier gauge rod than standard for nos. 1 & 5 etc.? I notice that the lower leg profile is more like the...

Hi Robbo: Only the upper leg profile is more angular - otherwise, not much else. The later COMPANION stamp is simply an outline, whereas the...
You will find the six-digit date stamp at the bottom of the burner riser tube: the last two digits are the year of manufacture; given the round,...
That's a late one: I remember them still being sold new around 1968. Peter
