Hi Adam,
With regard to the map, which Frank assembled from assorted scans, and re-drew, (THANKS) which formed part of the IGS 1986 information pack, shows the factories and organisation of the glass corporations as they existed in 1985. Borske Sklo would not be shown as it became part of Crystalex in 1974.
Bohemia Sklarny had several factories, as lead crystal production was re-organised @ 1950, Podebrady glass works, Nizbor (formerly Ruckl), Josefodol at Svetla nad Sazavou, and Antonindol, (Jihlava), as well as various other small workshops. The cutting of Zahour's new designs was done at Podebrady, but for virtuoso cutting, the workshop at Usobi remained the centre of excellence.
Beranek(Skrdlovice fell outside the remit of any national corporation.
Moser (shown in blue) was a part of VHJ Crystalex. Its marketing was carried out by Crystalex and Glassexport.
With regard to Harrtil, are you asking whether more than one colour used in a piece or the range?
Certainly there are five designers known to have produced work in this manner, and not all of it necessarily made at Harrachov. It is alleged that some was made at Chribska (Chribtil?).
No source is ever flawless, and I am just as prone to making errors as others.
regards,
Marcus
