Hmmm I'm not so sure Pamela, as mine has a 1950s style chrome stand and a bakelite / old plastic knob on the lid, so I think it's older. Plus the spoon is pure 1950s as well. There are scratches on my pot which fit the metal holder, so they've been together a while I think.
Oooooh I've just had a thought: I've not checked the spoon for a maker's name - that might help pin a date down closer.
