Hi, here are some photos of an Optimus 48 I restored two years ago. I lacquered it at that time but didn't get around to photographing the stove until this evening. The Op 48 is a 1.75 pint, paraffin ( kerosene), collapsible stove with a silent burner. Its sister stove the Op 45 is perhaps more common and it has a roarer burner fitted as standard. This particular stove is fitted with an Optimus patent "igniter", which you will see clipped onto one of the burner tubes. As with many Swedish stoves, the graphics on this Op 48 are beautiful: Best Regards, Kerophile.
