Long Arm of Coincidence: I commanded 1340 Flight, RAF, from Mar'45 to Mar'46 (Any relation to the 1340 Flight mentioned ?)
I think they're one and the same - issued by the RAF when they need to identify a "Flight" for a relatively short time rather issuing a full squadron number.
The full title of the flight in Kenya in the 1950's was "No. 1340 (Harvard) Flight."
A more in-depth article about the activities of the flight in Kenya can be found here:
