This is a spirit stove manufactured by Nyköpingsverken in Nyköping, Sweden. It is called Säkerhetsspritköket KOMA. I do not know when it is made but I would think about the '50s or '60s. It is made in aluminium and is a little different than burners of the Trangia type because the filling hole is to be covered by a steel lid so the spirit is vaporized and burning only in the holes. This stove is missing one of the pot stands.
