That's as close to a flame shot as is going to be available for some time. But it is what it is, a rather care worn example of a stove which has so far only been seen in this 1934 advert which @optipri had posted: If paired up to be a double burner this would be the right hand side unit. This is not the easiest side for a right-handed person to pressurise, so maybe purchased as a single by someone who was left handed or just didn't have an easy location to place a stove configured the other way round.
A little progress with this neglected project. The original 'Leone' burner finally removed, cleaned out and treated to a new jet. And so, at last, a real flame shot and cup of coffee. @z1ulike
