Hi Björn,
My Petromax is nowadays still functioning very well, in fact it operates like a Buick, you now the famous American car that is allways going strong!
But I have looked at those double hole Petromax mantles and the two hole mantle holder.
Please, advice me, are these twin hole mantles much better than the standard ones? Is it only a question of durability or will this two hole mantle also give an even brighter light?
Best regards,
Kenneth from Finland
