Ah yes, I also remember G KATE, and G OGAS and G BIWY which was nicknamed "Winkee Wanky" by the AFISOs at North Denes (a fine bunch of Bristow guys who used to keep the whole SNS de conflicted in the days when Coltishall was closed and Anglia Radar was but a distant dream)
I digress, I am missing a W30 here, because there was 4 of them I think, was it G BKGD?
It could have been such a good machine with some development, and dynamic improvements.
