I think the profile of "Hien" s/n 4024 at March 1945 .... is incorrect. These red quick ID strips and the front of the wheel doors are probably a wishful thinking of the author only or just wrong rendition of an image taken with the ortho-material. I think the "Blue 24" is shown in these pic posted above. It is clearly seen that the leading edge of the wing and the main wheel doors are of light colours. If these would be of the red , these were as dark as the Japan Hinomaru or just like the strip on the fuselage ( if it was red too ).
