The T-6 has a nice cockpit with a tubular frame. I painted the interior with Modelmaster Interior Green enamel, with panels in matt black. Details were picked out with a silver and a white pencil, with drops of Future on the instrument faces. I used the silver pencil to show some wear along the seats and rudder pedal troughs. As I wanted to model an SNJ,  I needed to deviate a bit from the kit's directions, which are well written and tell you how to modify the kit to look like the racer. I found several pictures on the web, and also found that the Decals Carpena directions were an excellent reference in getting the correct details in place. I chose to model an SNJ-4 as used 15 mile from me at NAS Alameda, in 1943. That meant omitting the rear gun, adding the radio mast (included in the kit) and using an engine cowl without a gun port (included) I replaced the molded in pitot tubes, that I managed to snap off, with brass wire. The kit provides dropped flaps which I used. It went together well, although I did have to check the fit a bit when placing the interior cockpit frame.  I needed to use Mr Surfacer on the seam between the cockpit and the tail, but the rest of the seams closed up snug. The canopy sections were cast thick enough that I chose not to mount the front cockpit canopy, as it rode up high on the mid section.

For the P-51 I again ignored the directions to demilitarize it, choosing not to remove the gun ports, etc. The cockpit went together easily, and I added a set of etched seat belts. I used Modelmaster Interior green inside, picking out highlights with a white and silver pencil, and some bits with red paint. Silver pencil was used to highlight the edges of the radio boxes in back and the seat framing. I painted the floor brown, then while still damp, pulled some tan across to get a plywood look. The headrest was painted with a leather color of Humbrol enamel. The panels were done in matt black. The gun sight is pretty bad, but a bit of filing and paint helped.
