The Schellville DC-3, 2002
N139D has been parked in Sonoma County, California, for a long, long time. It's still there, in 2008.
This DC-3 (serial no 2165) was manufactured in 1939, and here's a history of the aircraft:
"This one is special ! N139D is a DC-3DST-217A a.k.a. Douglas Sleeper Transport, the original and first series ordered with Douglas. One of the first things that catches the eye is that the door is on the righthand side, whereas on all the other DC-3 versions, it is on the other side (which became standard, due to airport and parking facilities). cn2165 was delivered to American Airlines as NC21752 "Memphis" on August 30th, 1939. It went to war as 42-43620 designated a C-49E. It was returned to American Airlines in 1944. It served with Colonial (1949/50), Owens Illinois Glass Co. in Ohio, Ohio State University (N110SU, 1969), Nevada Airlines (N139D, 1975), Pacific National Airways (1980), Mr.P.Grossman (1980), Crocker Nat'l Bank of Orange,CA (1982). It was owned by a Mr Lee Schaller when I photographed it in 1996 at Schellville(CA), but apparently the cost of insurance is keeping this Classic Dak on the ground."
A sister aircraft of this DC-3, the former "Flagship Knoxville," was restored in the 1990s and is now on display in the American Airlines Musuem at Dallas Love Field. So during the early 1940s, this aircraft would have looked something like this: exterior and interior.
