Edgwick lathe
Pete.:
No way on earth would I be spending £1.5k on an old Edgwick, especially from a closing down company. It might be a minter but it's probably well down the road towards being a wreck.
I don't know where you are Faz but this 13" South Bend was on sale in Peterborough recently for half that and it's in superb condition, still has the scraping on the ways.

Hi Matt,

True enough, it'd be easy enough to make a back plate. Bear in mind, though, that unless you want to try to fit 3 bolts through the back of the spindle nose, whilst holding a chuck in the right place, then getting it to seat properly on the register.... you need to put 3 backward facing short-ish bolts through from the "wrong" side of the backplate, trapped in such a way as they can't rotate when you crank up the 3 holding nuts...
As for the spindle taper - proprietary it may be, but it's exactly 0.050" per inch, or 0.600" per foot, which is exactly the same as a Jarno taper... Trust me, I've had a bore gauge up her snout... I made (bodged, really) an ER32 collet chuck - out of aluminium, which is hardly the ideal material - and as soon as I got the taper right, it went in there snug as a bug in a rug. In fact, it took a pretty hefty thwack with the LART* to shift it...
*LART = luser ("loser") Attitude Readjustment Tool. AKA a hammer. luser is an old Unix joke.

I used lengths of stud, threaded int the back plate, with a tack of weld to stop them coming unscrewed! As for holding up the chuck, I use a wooden "horse" (one for each chuck) so that it is supported, no weight! It also protects the ways from chuck fall! You could use counter sunk bolts coming through from the front! Make the threaded part short enough to be able to get the nuts on when the chuck is fully home!
