After searching all the photos that I could access, I *think* the answers to your questions are: Fuselage decking – flat gray black (Nakajima style) I did not notice an under canopy antenna on my searches. The interior canopy framing would *probably* be the same as the interior – PollyScale Weyerhauser Green from their Railroad Acrylics line. Re: Nate Rudder In Color *PIC* Posted By: James F.

Three of these rudders are in existence from the No.77 Hiko Sentai and all three wre taken as trophies by members of the AVG! One is on display and two are held privately.
