Raising a new topic, rather than piggy-backing the debate about the Ebay advertised 1961 roadster, Jerry raised the question of the J64 prefix to his 3.8 E-types Car No./Chassis No. to give an J64889791 Identification Number as recorded on his Californian Registration papers. As I have said the fact that the State of California chooses to list this Identification Number under a pro-forma heading of a VIN, is merely a matter of current Californian convenience, as it is not a VIN, given a VIN is a legal term as laid out in two internationally compatible (but different) standards - ISO for all of the world apart from North America, and SAE for North America only.
But I have to say, I would love to find out the local Californian logic/basis for these added prefixes - off the top of my head I cant recall when they first appeared - maybe J61, but I definitely record several with J62, J63, J64 and so on up to J70 being the last I record ? Does anyone know for sure?
And at what point were the J62 up to J70 tags actually added physically to E-types. Were they fitted by Jaguar Cars New York (on importation), or given they were only required for Californian cars were they actually added by the actual Californian Distributors Hornburg or the individual Californian dealerships. Certainly not fitted at the factory by Jaguar themselves. And confusingly, there have been some instances of E-types with these added J62 etc prefix/tags apparently sold new into States other than California?
I also wonder what was their significance was in 1962 (or 1961), as this predates any particular special build requirements for California, being no different (for Jaguar at least) from overall USA peculiarities (such as all white front side-lamps, and all red rear side-lamps, rather than the RoW Amber coloured Direction Indicator Lamps).
Certainly the Californian peculiarities came later re emissions requirements, but again Jaguar built one USA specification that suited all USA and not just California.
But Jaguar only got interested in any need for special USA identification with Series 2 E-type, with the 1R prefix used for all RoW markets, being allocated to 2R for USA only, then the UC, UD and UE prefixes added to the 1S prefix of V12 E-types (but never for California only as per the J62 to J70 tags).
Does anyone have a reference/link to anything that discusses/describes Californian MODEL YEAR regulatory requirements in these J62 to J70 years, as it seems apparent that these added pre-fix tags relate to a MODEL YEAR requirement for legal registration in California. The whole system was much more formal and obvious, if indeed a LOT more complicated for the USA 1968 Model Year Emissions/Safety requirements with special plaques added to USA market cars, so I wonder also why California still retained an overlapping J68, J69 and J70 prefix tag to Jaguars CAR/Chassis Numbers.
There MUST be someone who understands/is expert in 1960s USA and Californian Regulatory requirements - surely not my place in Australia to work it all out - but simple observations are just that, observations. There will be documented Regulatory requirements - somewhere.
