Great photos. These French Aeronavale Lancs were supplied as part of the Western Union agreement and the aircraft later wore WU numerical codes. Here's an example of the last colour scheme these aircraft wore whilst based in Noumea in the Pacific.
This is WU15, originally NX611, today known as Just Jane and owned by the Panton brothers at East Kirkby, Lincolnshire. Four of the surviving Lancasters worldwide are ex-Aeronavale WU aircraft, one each in Australia (WU16), France (WU21), New Zealand (WU13) and the UK (WU15).
The 1944 Lanc is an early Mk.I, note the smaller bomb aimer bubble.
Ops, Dear Boy, not 'Missions' (said in a clipped English Home Counties accent ). That's R5868, the RAF Museum's aircraft, in 453 Sqn RAAF markings with the legend "No enemy plane will fly over the Reich territory" on its nose aft of the ops tally.
