Stevet, congrats on buying what looks like a very original tc. I owned a 46 model in the early 50's which was also black but with beige upholstery the wheels as ex factory were silver painted, as stated elswhere the grill always matched the interior colour.
Before buying my 1st mog about 20 years ago I totally rebuilt a lhd td, [tds were the first midget to be offered in lhd form] took me 4 years: then ran it for a couple sold it and bought a 79 +8 which now resides on the continent. I now have a 3ltr roadster.
