Ingold mentions two major types - one with, the other without millefiori. The image in the book is one with millefiori, top and 6 side facets. 6 different base colours are mentioned: dark blue, turquoise blue, red, clear, plus blue and red jasper ground. Some 1300 weights (all together) were made - to be sold in the US only. Only a single overlay weight (white) is known - in a private collection. No weight with QE2 and DoE together is mentioned.
