So it looks like i'll be able to take this dizzy apart and give it a good clean however it needs a new Rotor Arm, Dizzy Cap and Vacuum Advance (might still work but its badly corroded on the outside.
It looks like I can get a cap and rotor arm for it for £11.00 here but can't find which Vacuum unit to get for it? The one on it is too badly rusted to read any of the advance settings, so I am not sure how to go about a replacement?
The 65DM4 that I have is a 41975A and is not listed in the .pdf posted up by @Dusky in this thread
The closest on eBay is this one (mine is a 2 pin version).
Clean up the old vac can there should some pressure info stamped on it.
I was looking in the wrong place, it was staring me in the face:
54404057
150 180 9
Stamped on the side.
Can't find these anywhere in the Internet.
I guess I could replace it with a BAU5309 which is listed as a Cooper 1275 with HIF44? But I need to try and match the vacuum advance specs with another unit?
