Real classic kit Del although it's not a production version but an FDS frame. I remember building this in 1982 and listening to Girls on Film and was doing my first camo mottle effect with my new Badger which I still have today using canned air so squeezing off air was at a premium. I spent a lot of time filling and sanding as Tamiya kits of that time weren't as sophisticated. Turned out better than I expected.
Nicely airbrushed Del. Seam lines and joints are more prominent when an airbrush is used because of the thin coats. Watch out for these on your next aircraft build.
