Car sorted; purge value moved a little I’m told which stops the cause of the high pitched noise and an o-ring replaced on the tube / pipe connected to the clutch. I pick it up tomorrow so look forward to a sunny drive home. Service from Morgan has been great this week, informative and timely.
Car collected, all good / fixed. Apparently, I got to speak to one of the Development Team, they changed manufacturer used for the O Rings as they have seen a number of failures - the new ones have not failed. I spoke to him about the Rear Disc Brake on the American Super 3s. Yes, they do have this but it's not easily fitted onto the existing UK Super's 3s, but new UK / European Super 3s will in the coming months have it - it's a new braking system front and back, from the Plus 4.
