On the S1s, the only information available was the type (46 for S1) and the series build number: 46/0001-46/0299
S1a: 46/300-46/0541
S1b: 46/042-46/0644
Beginning with the S2 (Type 54), a little more information was given: 54/0645, just like above. But on a separate tag, the colour code was also given; such as L07 (Lotus Yellow). If there was a "+" or an asterisks, it meant it was a Federal spec Type 54: for example, +54/1846+. Somewhere early in the series, paint codes began appearing on the same tag as the vin rather than on a separate one. Beginning in late 1969, Federal Europas were now called Type 65, but followed the same system: +65/2475+.
Beginning in 1970, a new vin system was implemented. yr/mo/2 digit batch number/nnnn/destination. for example 7002112370P
The car as built in 1970, Batch 11, vin #2370 and "P" meaning: domestic RHD; R for Fed spec; Q for ROW, and PR for Fed spec Type 65 converted to RHD.
Beginning with the Type 74 (both TC and TCS), the system was slightly shortened, leaving out the day of the month.
yr/mo/nnnn/destination. For example, 73043856R. The car was built in 1973, April, vin #3856, Fed spec. With the exception of S1, S1a, and S1bs, paint code information is listed on the vin tag or on the early S2s a separate tag.
