Not really a stove, a Bunsen burner, but I see one has been listed before. As I was a science teacher for 34 years you can probably see the attraction. Complete with box, primer tin, spares tin, spares, instructions and tools. A little bonus in the form of a Primus primer tin.
@Robert Radcliffe Are you able to post the instructions in the Reference Library, please? Cheers Tony
That military inventory sticker confirms my old thoughts that the Radius 340 "Bunsen burner" was originally a Barthel design.
"Spritbr." is abbreviation of "spritbrännare"="spirit burner" MT=Med Tillbehör=with accessories M-number is the new style of swedish military inventory number introduced in mid-1960's.
