Thank you, Natalie.
Now we have the tray candlesticks, lidded pot and trinket tray, and green and pink versions.
There are some pieces (vases, bowls, baskets) with a similar looped decorative pattern on Marcus Newhall's Sklo Union CD-ROM pre-1958 Libochovice catalogue - page 8, patterns 3140 and 3141 - but sadly no trinket set pieces. May be a lead, though.
