Thanks for the good wishes. I picked the car up from the garage this evening. It seems it is a different part because it is Righthand Drive.
The big problem was the garage had not ordered the part last Tuesday as promised and so it did not arrive until this afternoon. Garage charged 120 Euros but the ferry and hotel cancellations cost me 200 euros. Anyhow car back on the road, which is all I needed. Incicdentely the damage to the old slave cylinder was 2 washers on the piston had slight cracks. In hindsight I am thinking it might have been possible to strip a l/h cylinder and use the new piston in the r/h cylinder. Just a thought, but it might save someone else a few days of misery!
