    Recently found Radius No.7 . It is in nice condition . Seems little used . Only a a small area of finish damage on the tank.

    This is the stove as first found . Dirty and coughing a bit but functional after only clearing the jet and giving the pump tube a shot of Ballistol .
    I drained the stove of what I imagine was old paraffin , cleaned out the tank by putting half a cupful of very wee stones used in aquariums in with some clean fuel and swirling . Got a lot of gubbins out .
    The burner got the full belt and braces «heat with airflow then citric acid ultrasound bath treatment». New pump leather , burner washer and filler cap seal . Original jet seemed okay and was refitted.

    Now looking a bit better. .

    The stove is marked AB Radius Stockholm . Made in Sweden on the bottom of the tank .
    The burner is marked Radius - Made in Sweden as is the burner cap .

    Cheers

    I'd say 1932 - 1937 (pre-Radius Ltd)

    Thank you Peter . I knew the A.B / Ltd marking was significant but couldn’t remember quite when they changed the mark. I’ve been lucky , its in good nick for a 80-85 year old stove

    Your No.5 is a magnificent stove . I am learning the history of these companies gradually . The Radius story is very interesting . I have a Nr. 1 s.or And several No 21. Seem very solid. This No.7 has virtually no wear. No scrapes on the tank only damage to the finish is a little corrosion. Very little wear or heat damage to the legs/pot supports . Often you find very rusted and pitted legs , these are nice ! I think tjis has spent most of the last 80 years packed away some place. The burner head is one piece the cap being rolled over the bottom mesh . Difficult to keep clean

    Radius was known for its innovative burners: there was the type "Excellent" that was included with the Radius No. 3 https://classiccampstoves.com/threads/1932-radius-catalogue-no-30.202/
    (introduced in the early 1930s, and discontinued in 1937 or so); the original No. 5 was distinguished from the No. 5 S:or by the burner: the No. 5 had the so-called UFO burner (same as on your No. 7), while the No. 5 S:or had the earlier, more familiar silent burner, with its separate inner and outer hoods. The Primus S:or models were introduced for quite different reasons (you can see it in the Primus catalogue from 1907 to learn the full story).

    Radius, founded in the wake of a Primus strike, always sought to distinguish itself from the estranged "parent" company through its innovations, including the earliest version of the self-regulating/cleaning burner (included on the Radius No. 6 and the 10 & 12 ranges).
