Hi Gaucho,
Mine doesn't look as good as you example, but here is my Nichimo Aichi E13A. The cockpit was scratchbuilt because the model was motorized, the only interior being a slab of plastic to hold up the shoulders and heads of the crew.
This bird was built in 1982, painted with
Pactra International Colors line of enamels. The nice thing about the model are the positionable control surfaces. Maybe the folding wings, though as shown, they are toy-like.



Basicaly, what you see is what you will get. The rear MG is awful (though the Nichimo B5N Kate's is pretty good).
Take note, it was built before I started doing much to fill and smooth seam lines--not the fine fit of the parts.
All the parts for the old girl are present, I just have to dig them out of storage.
