The 4 colour combinations for the HX 50th Anniversary model were:

Anniversary Gold over Contessa Gold
Anniversary Gold over Persian Sand
Anniversary Gold over Persian Sand Mk 2
Antelope over Deauvile Blue

maxsandman is pretty right. The 50th Anniversary came only with 202 Trimatic T-Bar, bucket seats, clock, AM radio, heated rear screen (sedan only) & rubber strips in the bumpers.

Apart from those items, the badges & the colour coded (Premier) hubcaps it was pretty much a normal Kingwood.
