It has the same control knob as the first Handi model Iron 1933-1934. The name Swift-Lite was also used on a Iron which followed the first model Iron.
@JEFF JOHNSON Hello Jeff. Thanks for the comment. I only scored this lantern a couple of weeks ago for $30 with a broken glass, lucky I had a spare for it. It is now the oldest Handi lantern in my collection as I do think it is the first version of the Australian made Handi SwiftLite Lanterns. Cheers Mark.
Hello Mark, this link shows the one Handi lantern which is part of my collection. Marko57 Handi Keropet lantern grey hood.
