Karl,
Yes, my Royal Blue (56) one came with Matador Red Leather (H12) when new. When I restored it I went back with a Shadow Blue interior that I scavenged from a wrecked TR4A in a junkyard. I prefer the Shadow Blue and the car will stay that way when I redo it although I'll have to think about the carpet. Not knowing that the carpet color matched the interior color back then, I went with black carpet.
