Small jobs
Well I took Malcolm’s advice and took the fuel sender apart. I did a practice run on the really corroded one from ROJ. Opened up it was just as rusty inside, and the casing almost crumbled away.
I was a little surprised by the basic nature of the mechanism - a reducing resister over which a flimsy connector would move as the fuel level changed. The question still puzzling me is why the damn thing doesn’t make the fuel tank explode! An electrical current going through a moving part within the tank?
Having done my practice run I then tackled the better of the two. I used my Dremel type tool to clean it thouroughly before carefully prising the tabs open and bending the outer case gently away to expose the mechanism. I removed the float arm and used the dremel again to clean the inside of the case, gently stroking the wire resister with wire wool and polishing up the connectors.
Before closing the mechanism up I coated it with petroleum jelly, which should protect it for a while.
More brakes
 I thought I would clean up and repaint the brake resevoirs before refitting. This is what they looked like before I took them off ROJ:
 And with one cleaned and polished, ready for painting:
I’ve polished them both up now and will paint them over the Christmas weekend - keep me out of the kitchen while the ladies do their stuff!
