The width of the cut varied widely over the years and over the labels. 
It is quite common to need a 78-rpm stylus for EMI LPs even into the 
very early stereo era; in contrast, even the early (US) Columbias can be 
played well with a modern elliptical stylus for 33s.

The ability to de-warp a recording depends on the vinyl used. RCA's 
Dynagroove recordings seem to defy attempts to apply pressure when warm. 
Of course, their deliberate distortion adds to the problem of getting an 
acceptable result. Still worse, it appears from the reissues that the 
distortions are inherent in the master tapes.
