I acquired this stove on the way to picking up this trove of goodies for @Tony Press in Melbourne for transport to Tasmania: Some Swedish New Old Stock This is my first encounter with a Coleman pump assembly: It has an un-embossed burner: Tank graphics: Base doesn't reveal anything: Today I completed its fettle and fired it up (it's stilly windy), before taking it inside: It works well: and there was no "sooting": It appears on pp. 15-16 of the second part of this Coleman-Thomas catalogue: https://classiccampstoves.com/threads/coleman-thomas-australia-catalogue-1950s.39043/#post-409083 and is very similar to this: https://classiccampstoves.com/threads/solus-no-531e-532e-1949-50.17220/#post-348490 Thanks!
