pdav,
open the headstock cover and look down inside.
There are 4 socket screws. A ball end hex key might reach them,
otherwise
the spindle will have to come out. The left rear screw is partially
obscured
by the V pulley. Use a 7/32" Allen Key.
All the S7 screws are Whitworth or BA (NOT Metric).

We are moving house and need to get my Myford Super 7 up the basement

headstock. Unfortunately, I have misplaced the handbook and need to
know what is involved in removing the headstock assembly.
