Anyone know about this? It's a 510, right?

What’s going on here? The base on the sedan says DATSUN Bluebird S10, an S10 is a completely different Dato!

So the image above is the 510 sedan with metal base and Real Riders. If I’m not mistaken that’s an ‘S’ before the ‘10’! Typo?

It’s correct on the 510 wagon, what gives? Am I missing something? Here in Australia the car is known as the DATSUN 1600 so this 510 name is a recent discovery for me.
