It is the 1986 catalogue and it is in there Amethyst Whorl, limited to 100 pieces and that weight was overstamped Edition Completed.
Would you consider sending photos for adding to Scotland's Glass please, front, top, base, best view and uncompressed on a light background please. I will make it a priority to get that catalogue contents up, as despite the small size of the images they are clearly good enough to identify as in this case :-)
