BRNC Chipmunks
An old notebook tells me that the NZ based Chippy (WK511) used to carry the code 905 when based with BRNC Flight at Roborough, Plymouth.
The complete list was:
WP795 901
WK634 902
WD374 903
WP856 904
WK511 905
WK608 906
WB575 907
WB657 908
WP904 909
WB671 910
WP801 911
WP809 912
As I recall only half a dozen or so were kept at Robrough with the rest in store at Kemble. Every so often they would be rotated to keep the hours fairly similar.
How do I know this trivia? Spent HOURS watching them (and the Tiger Moth predecessors) wandering around the circuit, wishing I could fly one... (and eventually I DID!)
