Actually the text of the instructions says the plane is from NJG 4 (which I think is where the roman 4 comes in), but the painting guide says NJG 5, which is one of the main reasons why I think the scheme is wrong (attention to detail is poor).
The fuselage code is C9 IV, and the serial is 730066. Based on the other scheme in the manual, I think the upper colors are RLM 75/74, and they just forgot the 75 on that page.
