    This nickel-plated No.1 came with the special (UFO) brass burner cap (No.4/33) which is actually termed by Radius as an ‘eldfast lågspridare’ = refractory low-spreader.

    As this No.1 S:or. would have originally been a roarer, I guess the owner decided (or maybe his wife decided for him!), a ‘quieter life’ was required - and thus fitted this ‘miniature sombrero’ burner….:lol:

    I have Radius’s steel version of the same cap (No.5/33) which I also use with this stove.

    As the stove did not come with a trivet, I added the period correct Radius trivet (No.1/68) I had spare, along with a Radius (No.0/92) pilot lighter (which Radius name
    ‘Eftertändare’ = Igniter).

    As the stove is stamped with the iconic Radius ‘Shooting Star’ and also has ‘A.B.Radius’ stamped on the base, it can be confirmed this No.1 was manufactured before 1938 - after which Radius became a ‘Ltd’ company, with ‘Ltd’ then appearing on the stove in place of the ‘Shooting Star’ and ‘Radius Ltd’ stamped on the base.

    Refractory Low-spreader (cap) stamping - yep, it’s a mouthful…

    Should it be called a ‘UFO’ burner or an ‘RLS’ burner? :-k ;)

    ..Perhaps just to give her husband a few extra minutes of sleep while she prepares breakfast or coffee.:-k:)
    A great example, and as always, excellent photos.
