240z vs 280z "Datsun" hatch emblem differences

[dutchzcarguy]

I have never seen a metal 240Z emblem, except of course the c-pillar emblems are sort of metal..

(zamac it's called over here, stands for zinc,aluminum and magnesium or something.. i'm not sure.. it's a combination / alloy ,of the most impossible metals, it has to go wrong.. and if old it does!  It rust from the inside out! there are bubbles of air in the metal that after many years start to look for an exit.. haha...)

I've got a feb. 1971 240z and it has plastic Datsun and 240z emblems. once i had a 1972 euro style 240z and that one also had plastic datsun and 240z emblems.
