I acquired this recently in Wagga Wagga, NSW. The tank appears to be nickel-plated brass. There is some additional solder around the base of the angulated hexagonal riser: The pump shaft has been replaced (by one too long): The filler cap is cast brass and incorporates the air-bleed screw (with a little additional solder around the base of the filler): It came with a SVEA roarer burner (which had a piece missing out of its side), that was completely occluded. I had also acquired another identical burner which I was able to de-coke: No identification markings anywhere: The NRV (despite replacement of its pip with Viton material) still has a slow leak, but it didn’t prevent firing up: A god flame after the nipple was replaced by a hypodermic-sleeved one: I thought that rather than double-posting (in Rusty but Running), I put it straight into the gallery… Thanks!
