I have a few numbers courtesy of Andy Graham (Lotus Archives) for Lotus Europa production numbers based on exterior paint color/colour. If anyone else could post any of the remaining numbers, it would be greatly appreciated.
Out of the 1834 Europa TCS imported to the USA, 424 were Black Gloss (L15), 255 Regency Red (L11), 163 Lotus Yellow (L07), 40 Olympic Blue (L26), and 9 Colorado Orange (L14). These numbers do not include the remaining 202 R-Code (Fed-spec) that went to Canada or Japan. Though I do know that a single Colorado TCS was imported to Canada. If you own it, you have one of one. I have one UK P-Code number: 250 Black Gloss TCS.
The only TC numbers I have are 93 Lotus Yellow, 82 Colorado orange, and 79 Regency Red. Olympic Blue was a late 1974 color only. I am guessing Ford Tawny Brown (L16) was built in relatively high numbers. Glacier Blue (L17), Roman Purple (L21), and Renault Mid green (L18) are most likely super low.
