Thanks for all the replies.
With the help of gomog I have established it’s the Beck variant, and frustratingly for me I can’t get under the car safely otherwise I would do it myself so my local ‘day to day’ mechanic is going to pop it over his pit and give it a bleed, but if it’s anything more than that I’ll have a chat with my regular Morgan specialist.
Another question, I’ve heard about stainless steel slave cylinders but I can’t find them. Can anyone point me in the right direction?
