    This Radius No. 21 is from the early 1920s. It has the following features which marks its production period:

    1. Radius before Radius Ltd (formed in 1937).

    2. A. B. Radius Stockholm/Made in Sweden on bottom of tank.

    3. Radius shooting star logo on tank and tin.

    4. Pressure release valve with external seal, straight knurling

    5. Filler cap with Radius Made in Sweden

    6. Non-recessed placement of filler boss

    7. Radius markings on burner.

    The features are consistent with the 1920 Radius No.21 stoves shown here: Radius No.21 - 1920; and
    here: 1920 Radius No 21.

    I pondered about keeping the stove with its patina, but some verdigris needed heavy treatment and the dodgy soldering at the filler cap needed to be redone. therefore there are photos included in this post from both the the pre-cleaning and post cleaning phases of this fettle.

    The tin:

    The tin needed treating for rust, but I photographed the remnants of the original artwork first. The lid had been painted with silverfrost some time in the distant past, and therefore had no remnants of the original printing.

    Radius is printed at the bottom and there are two stoves, one either side of the handle.

    After treating for rust I painted the lid gold, and clear-coated the inside and outside preserving the remnants of the artwork:

    Once again, the Radius No.21 is a great stove.


    Cheers

    Congrats on score.
    Thank you for an excellent reference post. A job very well done with stove and presentation :thumbup::thumbup:.
    Re Stejar's list of types 1 -6 yours is among a few examples that predate his Type 1 (ie the earlier tank lid), nonetheless the tank, this stove might be referred to as "type 1, earliest example". Of the other earliest examples, FYI Sam's shows the tin w/clasp & artwork. FWIW aligning w/your title "early 1920s", the 1920 catalog is 1st ref. to the No.21 and btw one "i had to have" back in the day and I did eventually get one.

    After seeing your photos @Tony Press , and following the link provided by @OMC , I had to dig out my, (not nearly so nice), Radius 21 for a look.

    Pretty nifty how designs change over time, and then too; how often do parts from a newer stove end up on an older stove? It’s almost as if a single stove, through a number of fettles, can come to represent the entire range of changes...
