My V-10p had a flanged spindle with three bolts holding the backing plate to
it. IIRC there was a short tapered extension on the flange that centered
the backing plate. To change the chuck, you removed the three bolts (there
was just clearance between the headstock and the flange for an open-end
wrench). The chuck and backing plate then just dropped off as a unit. I
haven't had that machine for over 20 years (wish I did, it was a nice
machine) so I'm writing this from memory and CRS set in years ago. On my
machine both the 3-jaw and 4-jaw had their own backing plates.

Your memory is probably in OK condition!
Mine has the flange with the three bolt holes as an integral part of
the spindle like yours was.
However both the instruction book and the parts manual show the
spindle as having a threaded nose. I presume mine is from a later
production?
The instruction book refers to machining the backplate in situ on the
machine to fit a particular chuck, which also attaches to it with
three bolts. It then states "A backplate which has been fitted to a
particular chuck should be left fitted to it and not used for any
other chuck, or on any other machine".
On these machines the chuck and backing plate must have to be
unscrewed to remove it. The OP's machine may be one of these.
