One of the plates donated by Maggie & Keith has been puzzling me. The first time I saw it, I thought 'Green Leaves': the pattern designed by Margaret Casson, 1958.
Then I started getting doubts: the pattern looks too modern... or does it?! Night Sky and Swirl look rather modern too and they predate Green Leaves.
The item was on a long rectangular 3-segment Sandwich Tray and conforms exactly to the right dimensions (13" x 5¾", 33x14.5). The white background may appear to be much later than '58, but Chance were using this on the one variety of Black Lace, c.1955 (or even earlier!)
The glass also appears green when viewed edge-on, but I think this is merely the effect of the white transfer.

Any thoughts, peeps?I've updated the site to include these images and made a few more additions and alterations.
