This Israeli Skytrain carries a serial on the rear fuselage, just right of the roundel. Unfortunately it is partly hidden behind a taped cloth, and the remaining numbers are very hard to read. Close examination of the original photo appears to show a "4" to the left of the cover cloth, and "28" to the right of it. Only one Israeli C-47 is known to match this, namely 4X-528 which was reported in the UK in 1954/1955 on delivery to Israel. This photo may have been taken during that delivery flight. No c/n is known for this 4X-528, and all in all the identification of the aircraft in this photo remains highly uncertain.
