Haller "Origineel" kerosene stoves were originally made by Georg Haller Co of Ottensen (Hamburg), Germany. Haller stoves date from circa 1900, but some variations (clones) were made in the former East Germany and are marked DRG. Production apparently ceased by 1975.
Haller stoves are of enameled steel construction.
This Haller stove came from the Netherlands and is in exceptional condition. This is the 3 burner model but you more commonly see the single burner model. All of the models take the same size wick.
