Stu, that's my logic too. - I think it was just a period (possibly during the Nissan "Red" phase) when they decided to give the Japanese domestic cars their own individual badges.
People keep saying it's for Prince, but it doesn't make any sense to me that you'd suddenly put the badge from a company you acquired in 1966 on a car that was never one of theirs, and not on one of the same era that actually was one. - It makes more sense that they'd create a stylised P for Pulsar to match the other stylised letters on other models.
I'll just wait for the obligatory flaming now. :roll:
