So, after much messing around last night with plenty of heat and some era-correct penetrating oil that I happen to have (I refer to it as the creosote of penetrating oil, black and probably highly toxic, but works!), I managed to unscrew the damper...cone?...from the fork leg and slide the rusty pile of everything out.
Ironically, that spring was in good condition and scrubbed up surprisingly well, whereas the other (left) fork leg came apart easy, and bits started falling off the spring...new ones ordered.
Anyway, the stanchion was missing it's lower bush, which after cleaning the sludge out the fork leg, I'm pretty certain is wedged in the bottom of the leg...incidentally, the threaded stud at the bottom (which doesn't have a hole on either fork) stayed in the bottom of the fork let too so that's staying there.
The question is (thanks for bearing with me, it was coming!), does this mean the fork leg is scrap, should I try a long, thin chisel to try and bend the bush until it falls out, would cutting the bottom off and then welding / brazing it back on work (and remove threaded stud at the same time), or using a very long drill (or hole cutter with extension), and drill it out.
Thanks for reading!

your talling D 7 tye leg bottom its best taken to some one that can sortten PROPSHAFTS it needd s to go in a lath & cut away the weld at the bottom of the leg carfully bush removed after marking it up proply then aseble & weld up it has to be oil tite ,.,., poking long props in wil scratch the inside if it ant scrached allready
I have used a knife welded onto a rod to get behind the bush and make a gap then larger screwdriver shaped tools to bend it inwards
and it will eventually fall out
if I can find the photos I took at the time I will upload them
others have made a tool with a Rawl bolt you may find that if you search the Forum

This happened to me. What I did was to put some loctite on the end of the fork leg and pused it back into the bush. Be careful, not too much. Leave it overnight in a warm room. Then put an old spindle or a suitale bar into the bottom clamps. Hit the bar downwards, but make sure the clamps are tight or you may strip the threads. Take your time and it should work. The bush will have to be cut off and replaced. Good luck.

That's a really good idea jolon, thank you!
I was just about to run off and try that, but then I remembered the stud is still in the bottom so I'd have to screw in / out of that because whoever had them apart last time put it in the wrong way round so the nice hex end that would make it easy to remove is pointing down and stuck.
Same problem with a screw tap, nowhere for it to go. Tried something down the side of the bush and no luck so far.
I even looked up the melting points of bronze vs steel, but they're too close for my liking, and I've been struggling to find somewhere that modifies prop shafts, although there's an engineering company up the road who I'll call tomorrow.
Is the triumph cub fork leg the same (looks it) as there's a tidy look one on fleabay for not too much, may be a better choice?
