240c hardtop

ok thanks that clarified it for me.sombodie at some stage told me it was the first skyline to which it is not,i read that the first was in the 60s,

ok iv got a nissan,p230/datsun 240c hardtop,1971,i think where it says modle it has a K stamped,am i to understand correctly that what makes a nissan skyline is the offical taging or gt which became gl badging or is there a little more to it,this car has 4 on the floor and runs a L24 hitachi carb,can anyone tell me more about this car and if it fits into the skyline group.
