A circa 1920's No:00, 1 pint paraffin/kerosene stove. This model features the tank boss to hold the storage cap when not in use. The tin on this one has been printed with the name Carlowitz & Co, the Chinese & Far East distributors name but features an Egyptian scene on the back of the tin! This style tin however was the standard style for Optimus at the time & possibly one of the first tins with graphics that Optimus used as I've seen an example containing & showing the preceding model of 00 with bun-feet.
