This repaint is for the FSX version 1.1 JBK Boeing 307 Stratoliner and is in dds format.
In early 1942, the USAAF impressed all five of TWA's SA-307B Stratoliners, making modifications to extend their range, using them as VIP transports under the C-75 designation. These aircraft served until 1944 in the Air Transport Command with their TWA crews. They were rebuilt that year as SA-307B-1s and returned to TWA.
Cherokee (c/n 1998) was impressed from TWA in 1942 as 42-88623. Flew for a while with incorrect tail number of 288625 (Zuni) which is depicted here. Rebuilt as SA-307B-1 and returned to TWA as N1940 in July 1944.
This paint scheme would have been around June, 1942
