Just starting to catch up on the backlog of emails, yes I separated
(accidentally by leaving too long in acetone) the rear cloudy rear

contacted the supplier here in Switzerland who then offered to re-cement
it for a small charge. I used ponds cold cream to clean as much fungus
as possible before sending it away.
