The set is shown on Marcus Newhall's Sklo Union CD-ROM: Rosice 1958 catalogue, page 21.
The pattern numbers of the pieces and sizes are as follows:
tray 4509 - 34.5 x 24cm
large lidded pot 4509/1 - 11.5cm
small lidded pot 4509/2 - 8.5cm
candlesticks 4509/3 - 13cm
trinket tray 4509/4 - 9 x 7cm.
The catalogue also shows a perfume flask and a perfume atomiser bottle, both with diameters of 9cm, and both with pattern number 427.
Oddly, the printed catalogue numbers seem to have been crossed through and superimposed with handwritten numbers as follows:
4509 becomes 1020
4509/1 becomes 1024
4509/2 becomes 1024
4509/3 becomes 1023
4509/4 becomes 1022
Both numbers 427 remain as they were.
