Thanks Harrison, Vic and Wayne
Heres a small update.
Pic 1: Reference photo of A8-164 A-SK in flight. The photo clearly shows the aerodynamic fillet added to the top of the fuselage, just in from of the Navigator bubble. Not exactly sure why this mod was done, but my thoughts are that it was added to reduce buffet around the bubble. It would be interesting to know the reason. Anyway it is missing from the Tamiya kit, so I have added it with card. (Image Source:Avaition Heritage Museum of WA)
Pic 2: Here is the added fillet. I have sprayed the first coat of Foliage Green to the upper surfaces to check seams and details. Some small fix ups and it is all good to finish painting. I am using MM Euro Dark Green FS34092 straight from the bottle.
End of update. Happy New Year!
Cheers
Peter
