Nice build of the Hasegawa P-51 in 1:72 scale by Paul Janicki. Paul used the original Hasegawa kit from the 1970′s. He removed the guns and filled the empty shell chutes on the wing undersides, then filled and smoothed over the rather coarse fabric rudder and elevators. Not having any views of the cockpit, he left that to imagination and presumed it would have been made into a two seater but decided to create a ‘blanking plate behind the pilot seat and removed the head rest from that. The brown paint used was by Life-Color French Chocolat acrylic glossed this with several light coats of Johnson’s Klear (‘Future).
The cockpit is a bit hypothetical, but without details of the many two-seat P-51 conversions, the area was a bit of guesswork. Can anyone supply any good details and/or photos of a two-seat Mustang conversion?

Very, very nice !
Nice job PAUL!!..the bigger pics are OK.
You could find, on the “web”, some internal pics of dual/two seaters mustangs…
You can find two seat details also with “cavalier mustangs”: II & turbo III series, not only w’ TP/F-51D’s…on “real/official” 2seaters, the rear canopy is different in shape.
American fellas modelers might have pics or links; otherwise, you can copy details from a “cavalier turbo III mustang” scale model, this plane is 2seater : the brand “Heritage Aviation”(U.K.) makes this conversion at 1/72 and 1/48 scale…plus at ’72 scale you dont have to extra-detail !!
Another track is to go THERE: http://modelingmadness.com/reviews/korean/us/cleavertf51.htm ; ask the author about references he got to make his “ICM 1/48 TF-51D Mustang”
