We have two identical lamps available. Both in similar and very good condition. This light is documented in the 'Indoor' catalogue of 1971 and was available in orange or green. Indoor was the importer of high end lighting brands for The Netherlands. They were dealer of brands like Vistosi, Louis Poulsen, Arteluce, and so on. The catalogue has not listed the brand and designer of this lamp and therefore this remains unknown. The ripple structure of the glass goes very well with the orange color. The inside of the lamp is opaline for a softened light. Measurements given are for the orange glass.
