Green Satin was still fitted to the Victor K2s when I had the "pleasure" of working on them in the late '80s!
Great fun lugging the dustbins in and out of the "back hatch".... NOT!
All 3 Green Satin LRUs had to be replaced as a match set.
As far as I know it was not replaced or upgraded.
"Lusty Lindy" seems to still have Green Satin, the indicator is centre left:
