As Rob said, paint colours didn't necessarily change at model changes and if they did they were introduced before the new model was released..... sooo, late HQ could have "HJ" colours... there was a colour change midway through HJ which continued through HX.... HZ had two colour availability releases. HQ had several colour availability changes... from memory 4 rings a bell... early HQ, 2 x mid HQ and late HQ... I know of a few HQ's that were Absinth Yellow from the factory.
