Mfg. Date~Year Correlation

["Michael T." <carrera@frontiernet.net>]

Does anyone know if Triumph built cars for a specific model year or the date
of production dictated its year designation?

Specifically, does an early August built car get classified as that year's
car or the next?

I've seen November 1968 built cars classified as '68's.
Shouldn't August 1967 be classified as a '67?

Perplexed in NY,
