Hi Glen,
I managed to miss this while the site was down! Congratulations, fantastic find.
As Christine suggests, the Palm Tree pattern definitely appears here in Australia in the Crown catalogues. I've seen them in the standard uranium lettuce green, amber and clear. There are four or five pieces in my collection, but only three are easy to get to. Would you like pictures? I think they're slightly different patterns, but would love your opinion.
Cathy
