Decidedly it was the day of rarely met aircraft at Villacoublay... Here C-47 F-SEBE C/n 13467 having US serial 43-93544, and tail 20423 being its Certificate of Airworthiness number, was one of the two owned by CNET, a quite civil establishment being the Telecommunications Study National Center. They also owned Alouette IIs and one or several Bell 47 helicopters all based at Lannion in French Britanny.
This machine, possibly and formerly F-BEFN receives fore the round CNET logo: a large C containing an oblique climbing NET and if you delete the fuselage cockade and rudder flag, you probably have the previous owner, decoration being typic of Good Time DC-3s of Air France/Aéropostale.
