Raymond Loewy was responsible for the significant restyling work, and Rootes introduced the "Mark" terminology – strangely starting at Mark III.  This seems to be the time when they decided that the 2 previous models (1946 and 1948) would henceforth be known as Mark I and Mark II.

Externally, it's almost impossible to distinguish between the Mark III and Mark IV.  Almost all body parts in the Service Parts Catalogue for both Mk III and Mk IV have a common listing.  All Mk III headlamps are 5¾" diameter and contain a pilot bulb if the car doesn't have a sidelamp.  Mk IV headlamps never contain a pilot bulb, and can be either 5¾" or 7" diameter.
The most easily distinguished part is the radiator.  When viewed from behind, Mk III is recessed at top left; inlet and outlet pipes are top right and bottom left.  Mk IV has a level top tank; inlet and outlet pipes are top left and bottom right.
Mk IV saloon price in England – £395 plus purchase tax (advert in Autocar magazine, 17 November 1950).
