I recently located this in the "spare parts" drawer of an antique shop... It caught my eye because of the the "routing" of the riser tubes - I've never encountered one like it. I wasn't able to decipher the script in the fifth photo and currently don't have access to wire brushes/cleaning tools. I was unable to "unearth" any similar burners in the Radius catalogues... Thoughts? Just found this: Unusual Radius tubular burner !
@Rodger Willows that’s a pretty amazing burner, I never seen it before… Regarding the writings… could be Upplands Vasby? Nicola
Yes I know the 800/801 Svea burner, this Radius doesn’t seem to have a flame plate like the svea. Probably the earliest Radius roarer burner datable about the first years of the company? 1913/1914 contemporary to Svea 801? Wow Nicola
@Nicola Francesco Elia I am also aware of its existence, but have never seen a record of it. No patent number... It still exists quietly in the history of radius that we have not encountered. Maybe an Indian product could be a copy of this, but...
Agree with above, definitely a very close approximation to the Svea tube burn roarers which were just contemporary to the establishment of Radius after the Primus strike. Maybe producing 'generic ' spares would have been a quick way to establish some sales record? Ian
Thanks @igh371 and @multi-cho for adding your thoughts. Ian so it seems that you agree with the earliest years. Like for Svea, 1913/1914 seems an “aesthetically” coherent period and like for Svea (and others) the lacking of some documentation could be related to the WW1 period. The presence of the Arabic text maybe suggests a possible period, but I have no idea honestly. Nicola
@Rodger Willows , THANK YOU for posting this. A rare historic piece. abbreviated PAT APPL (patent applied for) Rodger might eventually confirm. That context introduces makers copying each other (as they did) and makers "applying" for patents to defend against the constant copying that was the norm. It would seem be Svea got the patent and Radius did not. This is an intriguing puzzle piece. I do not want to assume size, large vs small... is this No.1 / two pinter or No.21 / one pinter size roarer?
@Nicola Francesco Elia @gieorgijewski @igh371 @multi-cho and @OMC Apologies for delayed response. @OMC I think that you are correct with "PAT APPL". That was my first impression. In terms of size - it is similar to a No. 1 (Primus 128, R128, 4128) 2 pint. It's manufacture would (I assume) have been quite laborious with all of the bending required, hence the limited production and change to the more familiar style of roared burner. I'm currently back on-the-road, but willing to give detailed measurements, further photos etc if suggested.
Just re-igniting this thread (pun intended)! Today I had the opportunity to fire this one up. All I did was prick the jet and apply the suitably distressed flame ring before firing. All as one would expect so far Uh Oh! A faint puff of smoke at 1100 Applied the lighter and It is still roaring well despite the small leak Another brazing job on the way. Thanks!
@Rodger Willows and I spent some time recently working on this burner (and a few others). I silver-soldered a repair to the leaking tube, and we gave it a bit of a clean: It’s working very well now. As pointed out above, there is an example of this rare burner posted by @gunsoo in 2012. Having given this burner a clean, I will post it separately in the Reference Gallery to clearly show its markings. Rodger has left this gem in my safe-keeping. Cheers Tony
