DM thanks for the PM...
I have learnt the RN and RAF swopped Angle / Dale and that Dale was commissioned as Goldcrest in Sept 43 but some years later, when runway extension was impractical, and repair was too costly the Admiralty decided to put their effort into nearby Brawdy - which was also named Goldcrest (when Dale closed - It seems naval practise to call satellite airfields after their parent, rather than a heirarchical title... i.e Goldcrest (secondary) rather than Goldcrest (the second))
