Angryfish. To the best of my knowledge production of the ED trifocal ceased when the casting facility at SOLA in Adelaide shut down a couple of years ago. You can still "make" an ED trifocal however by doing it as a "Franklin" with a D-seg in the lower portion. I would also suggest that private labs may be the only ones that have any ED blanks left as SOLA (Zeiss) would have trashed all their remaining stock. Good luck finding them though!
