I guess this is one of those things you either know it or you don't. I don't. Could it be for a Tilley LPG ?? Next to a Tilley mantle.
@Anthony This is for an Tilley R1 Radiator, now I may be wrong but what you have may also work on the Tilley R55 Radiator. Cheers, Norman
The Tilley uses a mantle with a through hole. It looks like it’s from a Coleman propane heater maybe.
I’ve not seen one with a band and two flat lugs (top photo) on a kerosene Tilley. Cheers Tony @Anthony
@phaedrus42 , I assume you mean to go on a Petromax lamp. I like the idea that it may be used like that but I don't see that it would fit on a Petromax. I've looked into Coleman and Campingaz but found nothing. Again, the mystery continues.
LPG is the most likely in my opinion @phaedrus42 but it would be nice to be sure. The holes in the wire mantles I have always figured they were for letting the flame get inside the mantle. I had a wire one without the hole years ago and I would have to blow on it several times to get it to burn inside. Funny thing was it work quite well with the flame outside the mantle anyway.
Thanks @goldwinger11 , I did see that one and had a look for a catalogue for it but couldn't find one. I think you would be right but it would be nice to see it in a catalogue too.
