Lol I guess no one has built the Aoshima's. Anyway it seems KOPRO now own the Aoshima molds and at $12 each I just bought both. I was a bit nervous before I opened the boxes as the K2 box showed a K1 on it. Worst that could happen was I'd have two N1K1's.
But on opening its definitely a N1K2 and the fuselage and wings are very different in the wing to fuselage area. Very fine looking models too.
In case anyone else is thinking of building a 1/72 George I would highly recommend the Kopro/Aoshima models. Nice fine engraved panel lines with some very fine tiny rivets under the center section of the wing. 1 piece and multi piece canopy. Coloured Painting and decaling guide. Cockpit interior is about what you would expect Decal over panel, floor, with molded in rudder bar and molded in side panels, seat and back-panel.
I dont have drawings of each aircraft but each aircraft looks like a N1K1 and N1K2 George respectively. I have trial fitted the N1K1 together and it looks good.
So for $12 its worth it.
