I have seen ones in the UK with the which are 82 and branded as nissan. Datsun started the swap over in the early80s/later 70s. So some were datsun and some were nissan for some reason. Wasnt until mid 80s where all cars were nissan.
Also if you want to go really old in 1979 they made a prototype.
my first car car was a Micra K10 and was an A reg in white i was the second owner... and the car was mint condish!!! if i find some pix ill post them...
