This isn't the only aircraft he's pointed out issues with. 
With some, like the Ki-67, A-20(?) and Boston, hopefully they'll be remodeled properly. The G4M1 and He-111 on the other hand, I wouldn't hold my breath on considering that they are "new".
Ki-67 is tough so few books & photos to work with even from Japan.
You have reminded me though the Smithsonian never did reply to my request for information on the captured Ki-67's.

May have to resubmit that request four months is the typical turn around on that sort of thing.
Long since past that time frame.
