An older example of a Svea 15 dating most likely from only very shortly after c.1908. The key feature is the early format of tank bottom stamp with 'PATENT' across the centre where 'MADE IN SWEDEN' was placed later. All of the other examples of this sort of tank bottom marking that I have seen have been with the pre-c.1908 type of pump assembly with the leather backstop behind the cup carrier. This one has the post-1908 'standard' pump assembly, but in an early form where non of the components are either slotted or hexagon sided; hence I'm guessing at a date only a few years after 1908. The pump tube cap carries the Nybergs Patent Sundbyberg legend and the tank sides the large Cyrillic panel. Unfortunately the burner is a much later substitute.
