OK, I took the box out today, the bell housing / clutch assembly was caked
in mud:-(
I had the not so smart idea of rinsing it out with the hose pipe before
separating it from the engine. When I finally got the box onto the floor
water started pouring out where the spigot / input shaft comes out!! There
is a fair amount of lateral play on the output shaft, is this normal or is
something horrible worn in there? No grindy noises though.
My next move is to open the box & get a good look if there are any gremlins
hiding in there.

No, that's normal - the primary pinion (the shaft you're looking at) is
currently only supported at the rear, as you have separated it from the
flywheel. In the middle of the flywheel is the front bearing, a phosphor
bronze bush that's a light press fit into the middle of the flywheel. While
your in there make sure it's not too worn, though it gets little wear as
most of it's life it's not doing any work (only when the clutch is
depressed)
What you're most likely to have, IMHO is a gasket leak in the clutch release
housing, you do not have to remove the bellhousing to change that. There
really is not much else that can cause a leak of gear oil into the bell
housing, unless you're in the habit of driving downhill at a gradient
sufficient (30° or so) to make the oil pour down the primary pinion. This
can, and does, happen and the solution is to bring the vehicle back to
level. Oil will continue to come out the flywheel drain hole for days
afterwards as it can be thick by then, as well as muddy.
Also, in your case, I'd change the gear oil as you may well have water in
it.
