Die-cast Shinkansen E3 Tsubasa

Apparently I found something notable in our local online market. Someone is selling their used model of a Shinkansen E3-1000 series, and, of course, "I have to get that!" Here's what it looks like, two days ago.

I would say it has a decent weight, some scratches and marks here and there, the wheels are metal but rusty, but it's a second-hand, can't ask more (after all, it costs only 4 USD (90000 VND) for me!)
It has logo stickers on both sides, for some reason, because the real counterpart does not have such, but I appreciate it anyway, that's some extra recognition nevertheless.
What I don't like, however, is the yellow headlights. It does not look well on silver color of E3-1000, so I took some time and paint them black like how Plarail did. Looks much better.

Here's what the original packaging looks like. (I taken this from Google)

The thing is, it's extremely hard to find more info about this set, as currently the number 71 has been replaced with E3 with newer purple/white paint job. 
What we do know is that this is an N-scale model, the price would be around 1254 yen/11 USD/250000 VND

And it fits with the blue plastic track, but just barely. Here's it next to E3-0 Plarail Advance on the track.


Looks very good together, with Advance station, not gonna lie.
