Hard to say exactly where it is.  Just blasted the lens with a UV lamp,
though as the UV lamp is probally intended for parties etc I'm not sure it
is short enough wavelength to do the trick.  Can't do any harm though.

Suspect it is the latter - I've heard the fungus described as 'snowflakes'
etc, and it is nothing like that.  I suppose the best bet is to just keep
using it unless I become unhappy with the images it produces.  If it does
go too far I could try swapping the viewing and taking lenses, nothing to
loose at this point.  Like you say, probally not worth spending money on,
especially as it looks like one of the previous owners used a gritty rag
to
clean it.
