Marham has three "Gate Guardians" though only two can be seen from the gate! The Tipp't-up Tonka (on a stick), the Parade Square Victor (looking the wrong way!) and a back-yard Canberra - hidden on a back road. They may be more?
In the mid 80's there was a Gannet in 431 MU's lower yards - it was later sold to a museum - in Germany I believe - but I'm not sure.
Nobody's mentioned the Whirlwind at Odiham - I remember doing all the Mods required to get it ready to put into long term storage!!!
