Update:
FOB you are absolutely right... They just called from the garage, and it was broken exactly as you said.
And on a further high note.... The steering wheel and other parts from Simon had also arrived, so it should be ready to hit the road by mid day tomorrow...
Only bad thing is that the clutch is still broken... It will de clutch... but only just... So I will take it straight from the garage, to where I work, and fit a new slave cylinder.. and if that doesn't cure it, a new master cylinder...(yep.. I believe I single handedly keep Simon in business)
Should neither get the clutch going again, I fear the car will go into storage, as I haven't got the time to wait for MORE parts to arrive, and still carry out any major repairs.... but.. lt's see if it comes to that.

For now...... Im extatic
