    A Radius No. 22, nickel plated, likely from the early to mid 1930's. This is a later version of the first model 22's (non-discus, unregulated roarer burners, vent screw in fuel cap, etc) that were available in the 1920's. These 'newer' models had a discus-shaped tank coupled with the regulated silent burner # 10/36 with internal cleaning needle. No vent screw, they were designed to be run with regulated burners.
    This style of the 22's were in production through until at least the 1950's, as shown in this 1950's Catalogue No: 50. Different fuel caps and the most recent versions of the 10/36 burners.

    This one had no storage tin, pan ring, draughtshield or spanner.

    The regulated silent burner 10/36 (circa 1940's) on this one is a replacement for the original 10/36 that came with the stove. Different spindle design, both the handle and the stem. Affixed to burner with cotter pin. Original likely was worn, damaged or blocked so it was replaced ~70 years ago. Burner with 'RADIUS LTD', 'SWEDEN' and Arabic writing around the exterior of rim/skirt. Internal needle was fine and functional.

    Round, lightly-geared spindle knob labeled 'A.B. RADIUS STOCKHOLM' and 'PATENT'. Metal plate on spindle: 'RENSNING' - Clean, 'STÄNGNING' - Close.

    To get her safely operational she required one new burner washer (from Fettlebox, the original was cracked and leaked), new viton gaskets for both the center fount cap and fuel cap (originals dried, replaced with those cut from 1/16th" viton). NRV leaked, it was removed (no washer). No PIP (assuming original cork), the brass cup was torn and the threads of the NRV itself were stripped/misaligned. It was replaced with a good spare new NRV (with Viton PIP), added lead washer and screwed back into tank. Pressure tested with air, left overnight, tank retained pressure 24 hours later. Filled 2/3rds with kerosene, pressure generated, again left overnight, no leakage and pressure maintained 24 hours later.

    With the tank 2/3rds full with kerosene, double primed with methyl hydrate.

    The Radius 22 performed well, good heat range with the dependable 10/36 burner although the one she's outfitted with here was very well-used. Passed the rice cooking test (20 minute simmer) and boiled up water in good time. I particularly like the small details of this one, especially the chromed pump rod. A suitable draughtshield can be made out of a tin can or equivalent for use outdoors (and indoors as required).

    Hello!
    Tanks for yet another superb post. :thumbup: Crisp and well lit photos, and informative text, very well done :clap:
    I just hope that you will not take my nit picking too seriously. You see, you missed a N when translating the text on the spindle knob. Instead of "RENSNING" you wrote "RESNING" which translates to "erection" :oops: Sorry, I just had to point it out. Please forgive me.

    Best regards
    Stoveuser.

    Oh such a nice old stove.

    It has a lot going for it - regulated burner, nickel plating, unusual filler cap, discus shape and the Radius shooting star.

    Thanks for the wonderful set of photos and accompanying commentary.

    Looks like I have to nit pick myself too ](*,) . I wrote "svindle knob". It should be "spindle knob" I must find a way to deactivate this automatic writing stuff on my I pad :rage:

    Thanks for the masterclass in stove referencing, it's almost like having the stove in your own hands. I love that Radius logo.

    Thank you, and it's my pleasure to add to the reference gallery, especially of a model not currently posted. Keep building the knowledgebase to help others in their research, not to mention your own too of course.

    lol Stoveuser, thanks for the cor(E)rection!

    Great presentation of a very nice stove. I would assume 1932 - 33 given the looks of the fuel cap. The same style fuel cap was used on Radius 10 and 12 for a short period of time and then replaced in 1933 - 34 with a bigger patented version, at first with wings and shortly after without wings.
