This C-47's identity had been a mystery for some time but it is now believed to be C-47B 43-48886 c/n 26147. The aircraft had been converted to C-47D and EC-47P. It was operated in SE Asia by the USAF and was subsequently issued to the South Vietnamese Air Force who operated it with the code "WB" until 1975, when it was returned to the USAF who presumably issued it to Singapore. When once inspected on Sentosa it was showing traces of the serial 886 and the code WB. The aircraft also carried the number "707" for a while (as above). It was later scrapped. Info from the Queensland Air Museum.
