From Chris Davis – Hudson stepdown interior trim finish-

48-9 had the two-tone walnut wood grain.
50 Commodore & Super had two-tone leather grain with Supers slightly different for the light color in browns. Commodore only had two-tone blue.
50 Pacemaker had a grey basket weave looking grain.
51-2 Commodore & Hornet had blue or brown leather grain. There is a subtle difference in color in 51 - 52.
51 Pacemaker had a red toned leather grain that harmonized with the vinyl on door panels. You have the wasp there, all I have seen had leather grain, 51 super like the 52 wasp.
52 pacemaker & all 53-4 models all painted to go with interior.
