Nice shots Clint
The FE2b typifies what is basically known about it....nothing (well almost)
It was allocated to the units in France 30.10.1917.
However that allotment was cancelled 24.11.1917 and the aircraft was handed over to something called E1 Repair Section. After that...nothing....
The Handley Page must be G-EASO which was registered in April 1920 and was last heard of trying to make a first return flight from India to UK in May. The flight was cancelled and the aircraft was dismantled. It probably never even went to India. Officially its registration was canx in April 1921, but I doubt the aircraft "lived" that long.
