Hi, I thought I would share some photos of a stove I have been working on today. This is a rather rare stove I think; an Optimus No. 0 from the mid to late 1920s. The Optimus No. 0 is a 1.5 pint paraffin stove with fixed legs, which shares the same burner as an Optimus 00, 1 pint stove. The spirit cup has a dimple, again as shown for the 1929 stove. By 1939 it had been replaced with the more familiar "modern" version. The engraving on this stove is still sharp and clear despite its 70 plus years age. The filler cap is an early type and is shown in the 1929 catalogue/ spare parts listing. The pump size of the Optimus 0 is the same as on the smaller 00 stove. Has anyone else seen one of these stoves? Best Regards, Kerophile.
