As it happens I have an update on my cast iron disc problem; I picked up a set of three stainless rotors from Allbike Engineering in Greenwich late last week and got them all fitted today.
Before:

There are 27 M6 screws holding the rotors to the alloy carriers, the head of the very last screw just fell off as soon as I put the slightest pressure on it, look carefully at the break and the damage through corrosion (I think) is obvious.....you never know what these things are hiding.

Here it is with the new stainless rotors fitted......it may be that the problem with the pads sticking to the discs is worse than it needs to be on my bike as I am using sintered pads, but just getting it wet on the trailer on the trip home caused them to stick quite badly and I do recall getting a bit fed up with the amount of red oxide dust on the wheels when I owned it previously. The iron discs which were much rustier than anticipated where they meet the anodized spacer ring will be brushed off, greased and stored so it can always go back to original if need be. Bear in mind this is a bike with less than 5,000m on the clock from new that will have spent almost it's entire life in dry storage.
Here are the new front discs fitted, hopefully they will be a little more user friendly.

As an aside to this conversation, I was at the National Motorcycle Museum last week, they have a very original looking Classic, still wearing it's Pirelli Phantom tyres (I wish they would re manufacture them).....I took a couple of photos from several feet away of the engine number which looked like LE032 (or maybe not) and that bike was fitted with the later production round hole Spondon stainless discs which looked very neat.
The stainless replacements are not as nicely manufactured and finished as the originals, but if they do the job I'll be happy.
