Osram - GEC "Warmlite" lamp in "Old Gold"

In the early 1970s Osram-GEC produced two ranges of decorative coloured lamps in three shades, the "Accent" with its characteristic square-ish shape, and the "Warmlite", available in the same three colours but instead sporting a standard GLS envelope. Many years ago I managed to track down some pink versions of the "Warmlite", but much to my surprise this even more elusive amber/yellow version appeared on Ebay recently.
