It was muck on the front of the rear element.

Well, probaly foolishly, I tentatively unscrewed the front of the lens, on
the basis of if it looked complicated I'd put it right back.  All the
glass
elements came out and it was a simple job to remove the assembly holding
the rear element.  

Looking at the viewing lens there is similar muck on the front of the rear
element.  This one is a lot stiffer, I need to get a bit more purchase to
take it apart.  

Bit worried how muck, 'smear of grease' gets inside the lens like this.
