My brother-in-law and sister picked this up for in Ipswich QLD: It had already been polished: “Optimus” and “Sweden”: The base of the tank is ballooned to the point of raising one leg off the ground and wearing/flattening the central inscription: The NRV was stuck and required pump tube removal - twice! Beware, not all Swedish NRV’s are created equal… Up and running: Thanks!
Indeed, and one could also say "Beware not all LUX NRVs are created equal" The original iconic external NRV Lux stoves are absolutely bomb proof, some of the strongest and most abuse resistant stoves ever made. But these badge-engineered, Optimus-made wannabes, though superficially beautifully presented ... well, they are what they are
