This recently happened to me. The clutch master cylinder failed and I was able to procure a replacement from Morgan Motors of New England. There was a recent thread about the combined brake and clutch fluid. When replacing the fluid you have to bleed both the brake and clutch lines and replace all the fluid in those two systems. Mine was serviced outside of the Morgan dealerships and my clutch lines were never bled, only the brake side.
