I join our community with THANK YOU for providing your dated Radius 21, key timeline detail . I am also reporting this at same time (edit: the request is in). I will suggest the images just above and the dated instructions also be duplicated as a reference post. "I think" it is likely that will happen with nothing more needed on your part. Thanks again for your efforts, I know such *reference content is much appreciated. *it is the crucial life blood of our reference site
My pleasure! I don' know the history of the stove. But when I got it the tank and all the washers was dry. I don't think it has been used for decades. Everything is as when i got it. The cap to put on the top of the tank is (reserve lid) from another 21 with the same type 2 tank fitted with a ufo burner. The washer inside has Radius markings.
bump answer *my question above, re Svein's example above, inspection dated 07 02 1938 (7th of Feb..) and re Knee's recent example, inspection dated 20 03 1938 the two early 1938 examples are an exact match (no surprise), Per checklist above (tank focus): *Svein's is type 2: "made in Sweden" is to the left of filler, does have recessed filler. This aligns with Stejar's ref post Type 2 as well, 1934-38 [ ...probably introduced later than September 1934. 1938 or later ”Radius” became “Radius Ltd” ] > pre-"Ltd.": re all text on tank & pieces, "Ltd" is absent (chk bottom & burner btw). > tank has recessed filler > **filler cap and vent with double / diamond knurling > windshield (carries over from type 1) "slots and hatch" **Stejar covers the filler caps for these 2 examples. Filler cap reminder: the earliest type (type 0 added) as well other addl Radius 21 filler caps for consideration. ----------- The two examples above also confirm the tin in use c 1938. thank you
bump1 on-topic, re "model" revelations scroll up re a 21R and NEWEST detail: oyvindbl just posted an early rare model No. 11 (no tin. domestic? version of 21) aside from the "No.11" it seems the stove itself may match 21s of the same vintage? bump2 In the No.11 post/link above, re my "Your tin might be a match to very rare earliest tin also? (NOT just that it is yellow), closeup comparisons can be done" [there ARE now more pics of his tin TY] and about early yellow 21 tins: The "yellow" tins are actually yellow on gold. Sam's, RIP, Radius No. 21 - 1920s w/early filler cap & compact pump asm remains my suggestion for earliest known 21 & tin. The tin: The top has 3 men sitting around a 21. The back has X-country ski scene includes "TURIST KOKET". The front has an early latch, front pic seems much the same as later examples. ^^^ that suggested as the earliest, 1920, possibly earlier. ============= The rest (noting yellow tins from gallery) are early, differ slightly and i do not suggest a chronology. NOTE the top covers on the rest, iirc, are the same: these 4 may be a match? We may be able to guesstimate a year range for these 4 tins? that would likely apply to the earliest filler cap too (they all have it) and looks to be same early tin: Knee's Radius 21. Early Model The tin: The back X-country ski scene [ MINUS "TURIST KOKET" ]. oyvindbl Radius no: 11 and 21 ? his IS a No.11 stove but came with one of these early No.21 tins. The tin: The back X-country ski scene. Stoveuser jr.'s Radius No. 21. This time with a different box! The back X-country ski scene. Dutchmike's Radius 21 'Pirouette' The tin: top?, The back X-country ski scene. ============== and Twodogs Radius 21 (does not have earliest filler cap). The tin: i presume image shows the Front, not sure what to make of it (in sequence), it's the only one like it, i think. It "may be" just msng pcs and damaged (not unique) BUT myself, i don't see holes for latch or handle 1900 views
all, @Knee, Before i depart from this model discussion again (we'll be baaack). Might I *, **suggest somethings re tin clasp, for consideration. In-general all stove models that the maker provides a tin (option)... the tins, alone, can be a worthy of their own chronology discussion (pairing/link to (dated) stove examples when we can). I have suggested TINDEX over years (decades?), in this case... ... Radius 21 TINDEX. in-sequence > It's established RIP Sam's stove/tin Radius No. 21 - 1920s is earliest known 21. ""Sam's type 1 tank older pump and type 0 filler cap (tin & stove may pre-date all others)"" BTW "1920s" in his title not vetted against what has been learned in looong meanwhile. > Iani's stove/tin Radius No.21 - 1920 ""Iani's type 1 tank type 0 filler cap"" <-- this is same on yours Knee, right? BTW "1920" in his title not vetted against what has been learned in looong meanwhile. *Suggestion: Consider, given Iani's filler cap AND *unique (/early?) clasp on his tin, might it be candidate for next version of tin following Sam's? ---- > IF ^^^ that were the case... would yours/Knee be next version? Yours does not have unique (/early?) clasp. Knee's also a type 1 tank, type 0 filler cap. > No tin, Stefan's type 1 tank, type 1 filler cap Just posted @Remus1956 pre-1925? No.21 (also type 1 tank, type 1 filler cap) I think I found an older stove..radius 21 ** suggest HAVE A LOOK at his unique clasp. What to make of that? ================== ================= PS Compelled to mention, re Remus's, ANOMOLOUS 21 has no maker bottom stamping (/maker imprint). interesting. thx 2300 views
@OMC I just studied this topic. Thanks for your efforts and those of others involved in the research. I only now paid attention to the clasp of my can. In fact, in the 1920 catalog illustration you can see those spherical embossing on the clasp as in Iani's example. On the other hand, in the 1925 catalog https://classiccampstoves.com/threads/1925-radius-catalogue-no-15.15440/ ( where the clasp is as with my can) there is already a different filler cap (in my case, type 0). In view of the above, I think you may be right in typing my example for 20-25. With all due respect to Stefan's excellent study , I wonder if, (if ever) there will be an even older than the existing versions of R 21 we will call it type -1 ? It's amazing how much creativity RADIUS designers showed in changing/improving many details over a not-so-long period of time..
