Thanks for the precise and detailed identification of the unit. I knew it was 523rd Naval Air Group but I wasn't sure about its correct Japanese name.

Also thanks for that very useful link. I've been looking for something like this.
Kanji on my "Judy" seems to be a little simplified but I based it on the profile in the attachment. Maybe it's even better because more tiny details in such a small scale like 1/100 could give a little blurry effect.
