Nice one Lawdog! I love the brutish look of the George compared to most other WW II Japanese fighters. Personally I favor the initial mid-wing version, but that's because it looks "edgier" like how the Convair F-102 looks versus the F-106. Both the Shiden-Kai and F-106 look more developed and business-like in my eyes.
BTW I believe "Kai" means modified, perhaps based on the word "kaizo". I knew I should have payed more attention in Japanese school! And I have no idea of the odereing of "Ko", "Tei" and "Otsu". Oops, I feel Watanabe-Sensei coming at me with her ruler again! We nicknamed her "Bulldog Sensei" because of her pugnacious personality. Imagine an 80-year old Japanese version of Linda Hunt.
