I'd say it's not from the Matsumoku factory, but I'm no expert.
My reasoning is, it hasn't got the "Made in Japan, steel adjustable neck plate" neck plate, the bridge pickup isn't the 'staple' type, and it's very hard to see in these pictures but I can't see the little dimple markers by each control knob.
As far as I'm aware these are all markers of a Matsumoku build, but again I'm no expert, @Bassassin is your man.
Also I don't think Ibanez, as mentioned earlier, were ever built in the Matsumoku factory.
