G-CTKL certainly flies out of Biggin on occasion, noticed it on ADSB yesterday. Funny how Harvards were banned there for for noise reasins fofcquite a while, various ex Portuguese AF examples arrived there circa 1979, including BGOR, BGOU, TEAC, ELLY, JUDI, but not all of those acquired by Whoever came to the UK. .. I think there were 5 in the BGO* batch... Great place for vintage hand-me-downs back then, at least one Ju-52, several T-28s, a Caribou, a Varsity, half a dozen plus T-6s, Don Bullock and Ted White kept the B-17 and A-26 there at least some of the time, plus Shipping and Airlines imported some nice American classics.
