My TCS 2758R is a an early 73MY built in 10/72. It would have come with the 1970 (4 World Championships badge). Lotus won the Championship in October, 1972 and didn't issue the 1972 (5 Championships badge) till a few months later. So a 1973 TCS should have 1972 badges because the 1973 Championship wasn't won until Oct, 1973 and cars built after that would be classified as a 74MY. A lot of owners and dealers swapped out the badges to reflect the newer championships. You can't have a badge before the actual championship was won at the end of the year. So generally speaking 1969-70 S2s would have (1963,1965,1968 Championships) badges. 1971-72 S2s and 1972 TCs would have (1963,1965,1968,1970) badges. Early 1973MY TCS's would still have the (1970) badges and the later 1973MY TCS's the (1972) badge. Early 1974MY TCS's would still have the (1972) badge and later ones the (1973 badge). Like I said a large number of them were swapped out to reflect the newer years. When I bought my 1973MY TCS it too had a 1973 badge but how could a car built in Oct, 1972 have 1973 badge when it was built a week before Lotus officially won the 1972 championship. It must be some Time/Space Continuum thing.
